I need help. The GUI is confusing to me and I'm pouring over tons of threads, but something isn't working. Sorry if this isn't in the right part of the forum.
I am trying to assess von misses forces. It's a wheel. I'm trying to look at axial and radial forces to see points of failure. It is a multi-body FEM with different materials attached.
I have no clue what to do. Can someone help provide a step by step process? I can't get the Calculix to run because I can't seem to get it to mesh correctly. I can't seem to mesh the model correctly.
I created it in Solidworks and exported as a STEP. The parts are validated to be solids.
So I try to create a CompSolid through Boolean Fragment, but when I select Compsolid, I get some little red flag.
I know FreeCad doesn't support multiple meshes, so my next thought is to make it one unit.
- So I select all the solids and apply Boolean Union (seems most suitable... IDK! everything else ends up creating an error when I get to Boolean Fragment).
- I check that it creates a single compound and all the parts are still solid. Check. By this time it has created something called "Fusion" in the model tree. However, it has created a compound, but now it is one single solid, which doesn't seem correct.
- Then, I select "Fusion" and all the separated parts under the "Fusion" character tree and apply Boolean Fragment.
- Then, I select "CompSolid" from "Standard"
- Then, I select "BooleanFragments" and apply "CompoundFilter".
The geometry check yields "Wheel_FEA_Part_III.CompoundFilter:
VERTEX : 798
EDGE : 1340
WIRE : 637
FACE : 580
SHELL : 6
SOLID : 6
COMPSOLID : 1
COMPOUND : 0
SHAPE : 3368"
Which seems correct now.
I really appreciate your help.
