Cannot run Elmer "elmag" example

[giesbrecht]

System: Windows 11
ElmerSolver version: v 9.0

I'm attempting to run the Elmer example found here: https://github.com/ElmerCSC/elmer-elmag ... passFilter

When I run ElmerSolver.exe in the BandpassFilter directory of the repo, I get the following:

Code: Select all

PS D:\repos\elmer-elmag\BandpassFilter> ElmerSolver.exe .\Filter_Zhai.sif

I've opened an issue on GitHub - not sure which gets more traffic between this forum and the GitHub repo. Any help would be greatly appreciated.

Cheers,

I tested this with an Ubuntu 24 VM and got the same error message.

EMParam is a user function is has to be compiled to exist, Elmer has its own compiler in order to link into the Elmer librariesOn windows
it is made with

elmerf90 EMParam_WR28.F90 -o EMParam_WR28.dll

On linux dll are not used it can be an so or no suffix is needed

elmerf90 EMParam_WR28.F90 -o EMParam_WR28.so

Kevin, thanks very much! It would have taken me a long time to figure this out on my own.
