Re: Cannot run Elmer "elmag" example

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 EMPara...

Re: WhitneyAV / Solution trivially zero!

You have a mesh with non-conforming bodies, Elmer communicates data between the body through shared nodes or mortar boundary conditions.

Re: export stiffness matrix without starting simulation

You could just kill the process after it starts or try to use the solver control

Execute Solver = Never

there are lots of option such as always, after simulation, before simulation, never, ...

Re: Elmer-elmag example throws error

What if you change

Linear System Iterative Method = CG
Linear System Preconditioning = ILU3

to

Linear System Iterative Method = BiCGStab
Linear System Preconditioning = ILU1

Re: Error using CoilSolver

There have been several successful comparisons of FEMM and Elmer. However, it is difficult for many reasons. Units are usually a concern, although Elmer is unitless by programming, including constants and material values means units matter. You are also comparing 2D FEMM to 3D Elmer, Elmer usually d...

Re: Issue with ElmerGrid when Editing Internal Vertices

If I double click on the body it does a segmentation fault core dump. This may be a bug. However, if I go across the top of the menu and select models, materials, I can select body 2 and assign it properties. I can do anything to body 2 from the upper menus, but I can't double click on it. Double cl...
