Mesh

Altair Forum User

hello,

 

can anyone please let me know how does vonmisses stress and displacement(in optistruct preference) vary with respect to the change in mesh density or mesh element size.If suppose I increase my mesh element size from 1,2,3...50 (gradually the number of nodes created  gets decreased) how will this effect my vonmisses stress and displacement???

 

is it like stress and displacement are maximum when the mesh element size is the least i.e., 1 and gradually decreases as the mesh element size increases from 1???

 

Thanking you in advance.

Hi Sritej,

 

Please refer to chapter 9 in Practical Aspects of Finite Element Simulation (a Study Guide) to learn about meshing and its importance.

The book is free to download from http://www.altairuniversity.com/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/
