I am working on a design project which involves the analyses of a Formula SAE frame. I have modeled the frame in solidworks using weldment structures feature. The geometry is fairly simple with intersecting tubes which have been trimmed at the intersections. I imported this geometry into hypermesh in the .STEP format. I was successful in creating the 2D mesh. But when I perform the 3D tetrahedral mesh it gives me error elements and the 3D mesh is inconsistent, hypermesh is unable to choose the volume of the thickness of the tubes, instead it chooses the hollow volume inside the tubes for the 3D tetramesh. How can I solve this problem. Is there an alternative?
I wish to perform static loading analysis and torsion analysis of the frame
Hey Ali Kara. I was successful in getting it meshed in hypermesh finally. I modified the geometry. I had a lot of intersecting volumes. I was able to create one single volume.
A friend of mine did suggest me the method you are suggesting as well as using mid surfaces and then assigning them a thickness.
Thank you for your help though. Appreciate it.
hello saurabh,
Please take care at the weldment locations or else you will come across concentrated
Stresses If you model with tetrahedral elements.
