Elmer 9.0 version on Windows, errors

[zgrydn]

When I run the codes below in Elmer 9.0 version on Windows, I get errors.

---------------
Solver 2
Exec Solver = Always
Equation = MgDyn2D
Variable = A

Procedure = "MagnetoDynamics2D" "MagnetoDynamics2D"

Nonlinear System Convergence Tolerance = 1.0e-4
Nonlinear System Max Iterations = 30

Linear System Solver = Direct
Linear System Iterative Method = MUMPS
End
--------------------

The error output is as follows. How can I fix the problem? Please help.

Try entering:

UMFPACK instead of MUMPS

and let us know what happens.

The Windows version of Elmer is not compiled with MUMPS.

I am using slightly different keyword for selecting direct solver

Code: Select all

  Linear System Solver = Direct
  Linear System Direct Method = umfpack

Zgrydn, have you solved the problem?

I am getting the exact same error (as posted in https://www.elmerfem.org/forum/viewtopic.php?t=8407).

I have been using ELMER both on my office computer and at home on my notebook. Several days ago, I noticed that ELMER would no longer run on my office PC.

Initially, I was certain that the error was due to some incorrect setup values in the sif file, but now it seems it may have to do something with the system itself.

Please let me know if you have some feedback on this.

Kind regards,
Rok

Very few windows version have MUMPS unless you have taken steps to install MUMPS yourself, and that is not easy.
Other direct methods are banded and umfpack
if you cant use direct you can fall back to the iterative solvers

zgrydn, have you managed to solve your issue, if not - post your sif file, I would like to check some of your solver settings.

You could also increase the value of keyword 'Max Output Level' in the simulation settings, to increase verbosity of the solver output, that way you can locate your problem more precisely.

Cheers,
Rok
