2003 Cosmos 1

[WDickman]

Is there a way to get dimensional deflection info for a model by using the new Cosmos stress analysis add-in for SW 2003? The exaggerated deflection is fun to look at, but just one dimension would be great! Anyone found a solution here?

Are you speaking of the cosmos express tool now available, or the actual cosmosWorks plug-in? Regards,

I am assuming he is talking about, Express, the pretty sales tool(hook) that SolidWorks dangles out in front of us in 2003. BBJT CSWP

I am referring to the Express. The very light version of Works.

No, it does not let you have control over that.

Actually, I am quite surprised that they included that with SolidWorks. You do not have control over the element type and size, which is as basic as it gets for different types of analyses. Outside of pretty pictures, I would not hold any weight in the results you get. I am not saying the software is bad, but FEA was not designed to be used by everyone. It takes a fair amount of expertise in material science to properly model and analyze a model. That's my two cents... DimensionalSolutions@Core.com

I agree with you DSI. The full version of CosmosWorks seems very easy to use but understanding the output takes expertise like you have stated. To me, Express and Simulation are very well placed marketing tools. Spark interest, dangle the carrot. Also just think what they can do in a demo. Right out of the box even!

I have to agree with DSI too. Any FEA software can be helpful or very dangerous (not just COSMOS), as it will give you the answer to the question you ask of it. The problem is that you need experience & knowledge to ask the proper question to give you a valid answer. "The attempt and not the deed confounds us."

WEll I agree with all of you about a lot of things.... Personally I think that FEA is great tool for design engineers to help themselves design smarter on the front end to increase the chance that their parts will meet spec prior to submission to the high level FEA guys analysis. For that reason, I always position the tool as a suppliment to high level FEA packages not a replacement.

TO understand fully, and make educated decisions requires lots of education in the areas mechanical dynamics, stress, and strain analysis, and should only be signed off on by those who are qualified and certified to do so.

But to answer the original question of this thread ... No you cannot do that with this package... only with Cosmos works.

I started to work with FEA in 1992, with ALGOR. Now I am using CosmosWorks. I did not tested CosmosExpress (there is no need, having CosmosWorks). FEA is an important tool to check and optimise your design. It's getting harder and harder to be on market and you must allways search for new solutions and low manufacturing costs; FEA will help you to select solutions with lower costs but maintaining quality. But it's a very tricky tool. You must allways validate your analysis and that means run several models, with different meshes, in different conditions and check if the final model as a predictable and understandable behaviour and the solution is converging for a good one. So your FEA tool should allow you to change mesh parameters and refine it where needed, change de restaints and loads,..., to provide you with results to check the final study. Otherwise you should allways limit your studies to the simple cases and be very careful with the results.

YES, you can "get" the Total Deflection.

If you use Notepad or something and look in the "Results Folder" (Welcome Screen, Options) for a file with the extension ".OUT" (first part is the part name), you can see the max and min displacements, as well as the max magnitude of displacement. It will look something like this:

Maximum Magnitude of Displacement

Node: 1050
Max.: 6.0005e-007 Mr. Pickles
