Is it possible to drive FEM softwares with MatLab?

Dear All,

I have got an optimization problem. It is not so hard, but I would like to solve it with MSC.Marc&Mentat drives by Matlab. The problem is: There is a plate (dim:a x b x c) with a hole in the middle of the plate. The question is, which is the biggest hole that i can make for every thickness if the there is a mximum value of von Mises stress. I made a FE model that solves the problem only 1 time. So I made a proc file, and I changed initial parameters in it (radius of the hole). I would like to solve it in a loop, but I can' t write a program wich drives Marc, and compare data. I would like to see every data points (max. von Mises stress for fixed thick. with different radii and fix radius with different thickn.)

Thank you for your help!

If you can call Marc from the Windows command prompt, you can use system() to call and run the Marc executable. That might be the easiest way to address this. I have run iterative FEM approaches in the past using just this approach.
