fea models

[pro/life]

I have a large frame assembly, consisting mostly of I-beams, and a large baseplate. This assembly has some very loose tolerances designed into the components.

Our stress groups fea software is unable to calculate a frame if gaps exist.

So my Question is: is there a way to create an fea .prt that has the geometry of the assembly, without the gaps.

I have tried saving the assembly as a igis or step and importing it back in as a .prt and trying to fill in the gaps with extrusions, but there are hundreds of gaps and you mind as well create the .prt from scratch.

Hopefully this was clear enough, any help is greatly appreciated, and I use wildfire2

As far as I know, there is no solution to your problem. As the gaps between parts are generated because of improper assembly constraints (from engineering point of view and for proe if they are valid constraints even though not meeting the design intent, they are OK). Hence, there is no automatic way to fill the gap in Pro E.


By the way, if your model has only I beams and base plate/s, then why 3D models are being used for FEA? You can easily solve the problems with "Beam" and "Shell" elements. This method would considerably reduce the analysis time.

you can copy the solid surfaces of allthe components in your assembly and make a publish geometry from all copied surface components then createan fea.prt and use the published geometry to create the part for your analysis.
