Dear ANSYS Users,


I am doing an optimization problem by MATLAB which calls ANSYS (Mechanical APDL) for an analysis part in the DO loop (iterations) algorithm.
For a less dof.s problem (about 5,600 Dof.s), it works well (ANSYS run in the batch mode by a calling command in MATLAB). However, for more dof.s one (about 100,000 Dof.s) at the first iteration there is an error appearing "ANSYS program has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available".
I already reinstalled ANSYS, but the same thing happened.
Could you please help me on this problem?

Best regards,
Wyler
