CATIA GSA FEM Constraint Question
CATIA GSA FEM Constraint Question
(OP)
Hello. I am working on some FEA for plates with a radius in the middle. Please see the attachment. I am wondering if anyone has any opinion on whether or not my contraints are correct. I am fixing the model on one face, applying a load to the opposite face and constraining the bottom face in the Z direction. I am getting what I feel are accurate stresses in the results but I am adding holes in the mid-section on some other models and am getting some odd results when I do that. Thanks.





RE: CATIA GSA FEM Constraint Question
what do your results look like ? why "odd" ?
FWIW, i think it's better not to post .ppt slides, post the .jpg.
FWIW2, i think you should get a better FEA ! I think CATIA GPS is limited in how it lets you model. i would rather see the far edge constrained in X (rather than fixed) opposing the applied X load. a face constrained in Z reacts 3 rigid body motions, a face constrained in X also reacts 3 (but one is the same as a Z reaction) and a single point Y restaint is sufficient.
