Hi, all
I'm working on a structural optimization problem invovled with running numiercal analysis with Abaqus. Therefore, it is impossible for us to use the direct differentiation method to calculate the sensitivity of design variable. But I guess there should a way to get sensitivity analysis done numerically with Abaqus. Anyone know such information or give me a short instruction on that, I would highly appreciate!
Best Regards,

You can easily do that outside the abaqus environment
You can write a short module in FORTRAN or C to access the input as well as output of an abaqus simulation and calculate the differentials.
