open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

Is the MUMPS library required for a parallel run of ARTEMIS or does it also work without MUMPS? This is not really clear in the installation instructions.
I read somewhere here on the forum that you are having some trouble with the MUMPS library for application with ARTEMIS (6 months ago by sebourban). If I may ask: what is the situation with MUMPS now?

Scalar ARTEMIS runs perfectly, but we would like to do parallel runs for large meshes (>1000000 nodes).

Thank you in advance.

Hello,

The Mumps library is not necessary, you may just have to compile the library mumpsvoid. However in parallel you will have no direct solver, only the iterative solvers will work.

With best regards,
