Wheel Hub Simulation

Recommended Posts

Hi i need to simulate a wheel hub of a formula SAE with a 3D mesh but i have a problem with the element quality check. The hub has a diameter of 120 and a depth of 85 mm. I try with differents element size, differents minimum element size and other methods but the problem still remains and the simulation crashes every time.

Are there any ideal parameters to mesh it? Remember that the geometry is very complex. 

 

Thank you very much!

Hi Alberto,

 

When you say 3D elements, is it tetra or Hexa?

 

You can ignore the element quality check by turning off element check during analysis.

 

To turn off element quality check, Go to Analysis page>> Control Cards>> PARAM>>CHECKEL>> NO

Hi, sorry the 3D elements are tetra. Thank you very much for the advice. With this control card are the results realistic?

 

Ok i try with your advice and the simulation doesn't crash. But the problem is that the part with the not correct mesh is not analyzed by the program: the assembly is composed by three parts, every part is connected with the countact surfaces. One part is the hub, and this is the part with the not corrected mesh. So i didn't resolve the problem, what can i do?
