### Can I open more than one ElmerSolver simultaneously in a PC?

Posted:

**14 Oct 2017, 13:51**Hi dear Elmer designers,

I want to optimize the electrical machine with Elmer. Thus, many models with different shape and size should be calculated by Elmer.

I have tried the Elmer and MPI for parallel computation, but it solves even slower than only using a single CPU core for my model.

Now, I can use MATLAB to invoke the Gmsh, ElmerGrid and ElmerSolver to calculate my model. I want to know if it is possible to use MATLAB to run more than one ElmerSolvers to calculate differnt models simultaneously? So that during the optimization, different models can be calculated by ElmerSolvers in different threads or different CPU cores?

Thank you so much!
