In my last blog post I talked about how the new CAD technologies (like Synchronous Technology) will be very useful for FEA analysis and optimization. This time I’ll follow up with a practical example using Solid Edge ST2 and the new Simulation product.

After seeing a comment on the Solid Edge Forum suggesting (strongly!) that we should use more real parts for demos and blogs, I put out a call on twitter and the Solid Edge newgroup for some real parts. The first one I got was a sample part from AdTran which came to me as Parasolid X_T part file . I’ve not tweeked or modified the part in any way but I have taken some liberty with the FEA analysis mainly because it’s less important to the point here (I’ll try to be more serious about the FEA side next time).

The video below shows how a part can be modified and idealized for analysis in an easier way than can be done with a history based system. Al Robertson was good enough to do the voice over on this video.

Hi Mark,
The demo is generally good. It shows how easy to change remove geometry.
It was a real part but the force used was very small, only 1000mN? Unless it’s a tiny part.
Some description of the part’s size & usage would be good.

regards,
Roland

Hi Roland,

Yes, I got the same comment when we talked about this video in the Solid Edge discussion group. I got a bit over focused on the synchronous part of the demo and wasn’t paying attention to the forces I used. 

I definitely should have used a better force here!

Fyi, the default Force unit when one create a new part file is “mmN”. So it’s easy to overlook the unit. Though the unit can be changed, wonder why it was set “mmN” as default?
