Hello again.

I'm wondering which equation solver is most efficient for solving nonlinear transient dynamic analyses.

I've read the documentation and found out that iterative solvers are more efficient than the default solver (sparse matrix solver), but I don't know which one to choose.

If you implement "eqslv,iter", ANSYS chooses an iterative solver that best fits to your current problem. I've already tried to compare solving with the default solver and using the best fit iterative solver and extracted no benefits. I think that there's no much difference because the model was not big enough, but before I launch an enormous model I'd like to know if there is a real benefit.

I hope that someone can help me out with this one.

Best regards,
Miguel Soriano.
