Dear Andy, If you do not build the interface with Mumps, the default solver is superlu for moderately large linear systems and it switches to iterative solvers for large systems. Iterative solvers can be quite slow if the preconditionner is not very efficient. You can try to select linear solver and preconditionner. However, if you have a not too large system (less than 800000 dof I would say), you can still use Mumps, but using the sequential version (see the installation page of GetFEM). Otherwise, you can try the Python interface : it is very similar to the Matlab one. Best regards, Yves. Le 11/07/2017 à 17:06, Yu (Andy) Huang a écrit :
