Dear All,
I want mesh with 2D element for sheet metal part (dynamic analysis problem), should the meshing size at least four time the thickness of sheet metal? if there any link that i can read it would be helpfull.
thanks
Hi Mahfud,
Please refer to the forum post below:

Hi Prakash,
You said it would not be a problem with linear static analysis. what about the impact loading? some people said it would error generation.
See http://www.altairuniversity.com/free-study-guide-book/
and other FEA resources / books
Hi,
For impact, crash or any explicit analysis, characteristic element length is a parameter to calculate time step.
Please refer to RADIOSS theory manual chapter 5.
