Following
this post, I am trying to run ElmerSolver against the .sif file provided by Kevin Arden. However, I get this error message:
Code: Select all
ERROR:: CheckLinearSolverOptions: MUMPS solver has not been installed.
STOP 1
I have downloaded the binaries from
here. and used the
cmd/batch script to set up the environment.

I remember some posts in this forum on MUMPS and windows. Also the use of MUMPS is not a requirement for the Elmer solution, there are other options available. For direct you could use Umfpak or banded, or switch to an iterative solver.

Unfortunately not because most CPUs have 8 ore more cores. Using only one CPU core is slow and for multi-CPU solving you cannot use Umfpak.
MUMPS:
https://mumps-solver.org/index.php is not available as free download. You can only get it by email request.
It is sad that Elmer does not support multi-CPU direct solving, especially for the stress solver and eigenfrequency analyses it is much faster than iterative solving.

See the bottom of this post for two work arounds
