Hi, I'm seeking advice on best practices for meshing surfaces intersecting 90-degree angles using shell (plate) elements in Femap. The main challenge I'm facing is the appearance of high stresses at the sharp bends, which can lead to result uncertainties and failure in model validation checks...

Hello everyone, I am trying to understand and use superelement in femap. The model consists of a cantilever beam constrained from one end (Node 5) and the free half of the beam (node 15:node 25) is superelement while the fixed half (node 5: Node 14) is my residue model. I have listed 15...

Thanks, Blas for your comprehensive and insightful response. I am trying to learn about non-linear solutions.

Thanks, @Blas Molero for your valuable response. Yes, you are totally right, and now I understand that it is a nonlinear problem. I am new to non-linear analysis field. I want to run both a modal analysis and static analysis on a structure that is being stiffened with such pre-tensioned cables...

It appears to me that the problem is with the cross-section. So right now I have a 3.5m long beam with a 1.6mm cross-sectional diameter. Actually, it represents a pre-tensioned cable that is subjected to bending loads. (That is why I have modeled using a beam instead of a rod) When I increase...

Thanks for replying, I have attached the Femap model, it is fairly simple. Please have a look at it. https://files.engineering.com/getfile.aspx?folder=8b1baeec-829a-4361-9ddb-ecba51c1280e&file=simple_beam.modfem

Hi, I am trying to model a beam that has an initially curved shape. When I apply body force in direction perpendicular to the beam, it deforms unusually. Can anyone point to why it is happening and how to fix it? In the attached image, the white curve is the undeformed shape while the colored...

Hi, I performed a thermal analysis of a model In Msc Patrn/Nastran that included several Explicit Thermal MPCs. After getting the temperature distribution, I have changed the analysis preference type to structural. Is there a way to convert those thermal MPCs to structural MPCs, because they...
