How to find the right number of integration points in second order 3d finite elements?

I am familiar with finite element simulations and numerical schemes like the Gauss Legendre quadrature. I also know that the Gauss integration yields exact values for polynomials up to degree 2n-1...

What could be the reason for not having further low chi square value (better agreement) in my refinement result?

I have tried every combination of parameter changes and after that i have a poor chi square value. I can't get it lower any further. I know there have been a lot of discussion about Rietveld...

I dont know, that much depth .... Some of my friends are working on hyper-mesh and nastran and patran. I will ask them, if they know i will inform to you.....

Rui Xu

Thank you very much. I have done some simulation on nastran and patran. I will be very grateful if they can tell me how to perform a wrinkling simulation by using nastran and patran.

Matteo Zanoletti

For a real wrinkling probably is better use LS_DYNA than ANSYS, or AUTODYN (ANSYS software). But if you mean a buckling analysis on thin elements in ANSYS I just suggest to you to use SHELL163 with Belytschko-Tsay Membrane (KEYOPT(1) = 5). You have to make a structural analysis before and then attach a buckling analysis. If you search in ANSYS help everything is explaind in a good way.
