Beam Joints in COSMOSWorks

noreply@blogger.com (SimulationMan86) — Mon, 07 Jul 2008 21:30:00 +0000

The beam functionality is quite nice in COSMOSWorks 2008. For example, you can tell the software which beams to connect at end points directly, using a RMC (right mouse click) procedure that is not well-documented. In the image, you can see a purple-colored ball close to where the red arrow is located. If you RMC on it, in turn a small panel will post (as shown) to indictate the beams that will be connected at that location.
You can add more beams to that joint just by selecting them, and remove beams by selecting them again. There is no "ok" button, however. Just close the panel and click on the "calculate" button in the Joint definition dialog. Very handy!

Wrap Feature tips!

noreply@blogger.com (Addicted2Cad) — Mon, 30 Jun 2008 17:53:00 +0000

Ever wanted to create a wrapped feature and not have the sides of the feature extrude radially?

Well today is the day to learn a new trick.

If you select Emboss of Deboss, you can select a line, linear edge, or plane to set a Pull Direction. For a line or linear edge the pull direction is the direction of the line, for a plane the direction is normal to the plane. Leave the pull direction blank if you want the sides to be normal to the sketch.

“Some pre-selection still required”

noreply@blogger.com (Steve Erwin) — Mon, 02 Jun 2008 19:51:00 +0000

Ever heard the expression “Batteries not include, and some assembly required” or how about “Some pre-selection still required”

What if you want to Dimension to where the vertex of a fillet would have been.
Introducing the “Virtual Sharp”.

To dimension to a virtual sharp, you need to first insert a virtual sharp onto the model. On the drawing where you would like the "virtual sharp" point to be inserted. CTRL-select the two edges which would intersect if allowed to extend. Once the two edges are selected, hit the "Point" toolbar button, and a virtual sharp will be created at the intersection. The user can control the display of the virtual sharp by setting the option found in Tools, Options, Detailing, Virtual Sharp. The user will then be able to create dimensions to the virtual sharp.

CFD for Free! What?

noreply@blogger.com (SimulationMan86) — Mon, 02 Jun 2008 14:26:00 +0000

Yes. This is correct: CFD is free!
Each seat of SolidWorks has a seat of COSMOSFloXpress. You can be a CFD person right now and amaze your friends! The software will allow you to conduct what is known as an "internal" analysis. If you have a box that houses electrical components that need air cooling, you can track how the air flows over components or even misses some of them - thus you will be designing where to best locate the inlet fan for optimum cooling, for example. You need to build a lid on the inlet opening, and you need to build a lid on the exit opening in the box. A wizard walks you through the entire process. This is a cake-walk. I mean it.
Menu: Tools/COSMOSFloXpress.
You can view a demonstration video of the entire proces (free) at our hosting site www.screencast.com/tonysmicrotutors and navigate to the LunchWorks folder for the video.

You may be thinking: "What about airflow over a body, such as a car or a wing?". You can do these too - if you don't mind the "wind tunnel" approach. Just locate your model inside a box with an inlet and an outlet. Remember to put lids on the inlet and outlet. You can position the wing or other body such that it appears to float inside the box.

SW2009 Beta period right around the corner.

Have you ever wanted to get an early look at the next version of SW? There is normally about 200 pages in the What's New manual to read thru. SolidWorks is getting ready to announce the start of the next Beta program in the first part of June. There are prizes available for the person that helps point out the most problems. You can gets points for filling out surveys too. Shankar and I have both won prizes on the VAR side of things in years past. Right now my 4 year old is running around with my 40 Gig IPOD that I won. I think Shankar put most of his stuff out on Ebay. I am still trying to decide how much effort I am going to put into it this year. You can sign up for the Beta program and there will be more information on the SW website soon. Here is a link for more information: http://www.solidworks.com/pages/services/CustomerBulletins.html

Have fun and try not to hurt yourself.

Maintaining your Dimension Machine

noreply@blogger.com (anthonyd) — Wed, 28 May 2008 13:13:00 +0000

I have visited quite a few Businesses, some machine are well maintained,(properly cleaned) some are fair, other are embarrassing, if your machine is not well maintained (this means cleaned), this could void your maintenance agreement do to lack of. Debris could fall upon main components causing sensors to short out or jam moving parts.

Large deflection option for assembly contact problems

noreply@blogger.com (shan) — Thu, 15 May 2008 21:12:00 +0000

It is general perception that non-linear structural problems are usually associated with Cosmosworks advanced professional module. Cosmos designer package can handle large deflection for contact modeling. With large deflection switch turned on cosmos solver performs true non-linear calculation by applying loads in incremental steps and formulating new stiffness matrix with load increment. When you have models with sliding type contact conditions large deflection option comes in very handy.

Its normally recommended to run the assembly analysis first with no penetration type contact condition and large deflection switched off. After running the analysis look at your displacement plot in a scale of 1. When you can see noticeable deformation in true scale then turn on large deflection and run the problem again.

To consider material based non linear and non contact based large deflection effects please use Cosmosworks advanced professional module. When using large displacement solution for static studies, program uses automatic load stepping and you can only view the results at the last step which corresponds to the full load.

To activate the large displacement option:
1. In the COSMOS Analysis Manager tree, right-click the static study icon and select Properties.
The Static dialog box appears.
2. On the Options tab, check large displacement.
3. Click OK.

SWUGN Technical Summit in OKC!!

It is a 1 day user group with many specialized presentations. Please look at http://www.swugn.org/pages/summit/SWUGN_Summit_OKC.html for more information. The meeting will be held in OKC at the Biltmore Hotel on Tuesday May 20th.

Instant3D

noreply@blogger.com (Unknown) — Tue, 13 May 2008 15:45:00 +0000

Instant3D was introduced in SolidWorks 2008. Now, what does it do for you? It makes it easier for you to quickly create and modify model geometry by using drag handles and rulers. How do you turn it on? Click on the Instant3D icon in the “Features” toolbar.

You may have recently heard of something called “Synchronous Technology” from Siemens PLM. Sounded interesting, after all I am a geek. I saw their taped webcast. Some of the functionality they were showing looked familiar; it was what we can do with Instant3D. Here is some of this functionality in Instant3D.

Notice how with Instant3D I can select the end face of Extrude2 and drag it to the other side of Extrude1 and the boss becomes a cut. Also notice that I did not have to repair the fillet. This is the good news about Instant3D; you can quickly make drastic changes to your model without having to worry about how your model was created.

When you drag to resize the feature, if your cursor is over the ruler, it will snap to the increment marks on the ruler. The increments are controlled by your “System Options -> Spin Box Increments”.

There are pros and cons for any new feature. Now is the time to talk about the cons, or things you have to be careful of if you use the feature. In the video, you saw where I selected the end face and then dragged the blue arrow. This makes it too easy to accidently resize a feature. It happened to me at the worst time. I was beta testing the new CSWP exam. On the base extrude for the first feature, I accidently changed the extrusion depth and did not notice my mistake. This accident cost me the correct answer to the first six or seven question on the exam. My cost was the embarrassment of not passing the exam. If you make the same mistake, it will cost you scrap parts.

There is a SolidWorks System Options setting will help prevent most of these accidents, but not the one I made. Uncheck “System Options -> Sketch -> Override dimensions on Drag/Move”. This will prevent you from accidently moving a face that is controlled by a sketch dimension. In my example the sides of the rectangular boss are controlled by sketch dimension. With this option checked, I could select one of the side faces and drag the arrow and it would change the sketch dimension. With this option unchecked, I can still change the dimension, but it requires a deliberate action. I click on the face, all of the dimension associated with the feature that the face belongs to will appear on the screen. You will see a blue dot at the end of the dimension arrow head. You can change the dimension value by dragging this blue dot around. You can also just click once on the dimension text and key in a new value.

If you use Instant3D, I suggest that you uncheck “System Options -> Sketch -> Override dimensions on Drag/Move” to prevent most of the accidental mistakes. I also suggest that you submit an enhancement to SolidWorks to make this option to prevent you from using the blue arrow to change the extrusion depth.

Additional Power of Admin Images

noreply@blogger.com (Anonymous) — Mon, 05 May 2008 18:01:00 +0000

Ever thought of using an admin image for all of your stand-alone Solidworks installations? Solidworks has a great tool that allows the correct products, with the correct serial number, to be installed by windows login name. This ensures that every user gets the products they should and they don't have to keep track of the serial number they should use to install. The tool is the Admin Image Option Editor and works in conjunction with the new installation manager introduced in 2007. It is accessible once an admin image has been created, in the shared folder where the image was saved. The first Admin Image should be created with every product needed. Navigate to the sldim folder and select sldamdinimageoptioneditor.

Double click on this and an application will start up where users and groups can be set up.

To set up a user, the user name is the Microsoft Windows login name and the display name is anything you want. Then add the serial number for every product that the user should have installed.

To install the Solidworks products the users will browse from their computer to the shared folder where the image was saved and run the StartSWInstall HTML file.

COSMOSWorks Trend Tracker Notes

noreply@blogger.com (SimulationMan86) — Sat, 26 Apr 2008 02:45:00 +0000

A really nice component to COSMOSWorks Professional includes the "Trend Tracker". Use it often! What's it for? Well...such a deep subject, but not really. When you run a simulation and develop results plots. turning on the Trend Tracker captures all the results for you automatically. No more saving screen captures, writing down results, and creating folders and text files to manage all that information. Next, change your design and run again. Trend Tracker records all the NEW results and saves them for you. Next, change your design and run, yet again. Yes, all your results are saved - plots an all. What a MASSIVE time saver!

To use it: Right-click on the name of your study and choose "Trend Tracker". A new icon will appear in the simulation tree. Right click on it and choose "Set Baseline". This will gather all the data from the first run. Now you can change your model, run again (same study!) and Trend Tracker will record your analysis results. You even get graphs of things like weight, stresses, and displacements. Right click on the Trend Tracker to view the gallery of images for each iteration, go back (restore) a previous iteration, delete an iteration, and more. View the Microsoft Word "Trend Journal" (icon underneath Trend Tracker) to look at numerical results of all the iterations. Very nice. Much time will be saved...

SolidWorks User Groups

noreply@blogger.com (Nicole Walden) — Wed, 13 Feb 2008 17:38:00 +0000

Ladies and Gentlemen,

If you are not already aware of the fact that SolidWorks User Group Network (SWUGN) is in existence, please become familiar with them now. The group started because a select few individuals thought that users could use a support system of existing users. Each user has the ability to share and learn from other users through discussion forums and group meetings. Please take the time to become a member and hopefully you can both learn from others and pass along your knowledge.

When in doubt

noreply@blogger.com (Nicole Walden) — Wed, 13 Feb 2008 17:08:00 +0000

When in doubt of how to do something in SolidWorks, go search the SW Help Topics. Help is one of the most overlooked assets that the software has to offer.

I have learned additional things by researching topics through the help menu. IE Animation, Blocks, Weldments, just to name a few.

Please remember to use all the benefits SolidWorks provides to you and make the Help Files one of them.

Things to remember when upgrading, installing, or changing computers.

noreply@blogger.com (Nicole Walden) — Wed, 23 Jan 2008 20:47:00 +0000

1. Turn off * AntiVirus software before starting
This is probably the most important thing to remember and the one thing that can cause the most amount of trouble during an upgrade or installation

2. Download Service Pack updates overnight as they are large files.

3. When moving SolidWorks from one computer to another remember to go to Help->Transfer Activation...
