Good day kevinarden I have attached a barebones mesh and program. Download all 3 files in the same folder and execute ElmerGrid 1 2 rect.grd ElmerGrid 2 2 rect -partdual -metiskway 2 elmerf90 volt.F90 -o volt.so mpirun -np 2 ElmerSolver_mpi case.sif within that folder. The program will freeze almost...

For case.sif, I added Max Output Level = 20 Max Output Partition = 2 in the Simulation section and with its Solver 1 Equation = "potential" Variable = -global Whatever Exported Variable 1 = -global setflag Exec Solver = Always Procedure = "volt" "voltage" End Solver 2 E...

I did ElmerGrid 2 2 meshdirname -partdual -metiskway 2 and output shows no errors and claims it was successful I can see the 2 partitions under subfolder partitioning.2 of folder meshdirname If case .sif contains something like Header Mesh DB "." "meshdirname/partitioning.2" End ...

Good morning I think the code is running in an infinite loop when I execute mpirun -np 2 ElmerSolver_mpi case.sif where case.sif contains Solver 1 Equation = "potential" Variable = -global Whatever Exported Variable 1 = -global setflag Exec Solver = Always Procedure = "volt" &quo...

No can do: if you write Restart File = "case.result0" you get Could not open file "./merged/case.result0.0" Could not open file "./merged/case.result0.1" Could not open file "./merged/case.result0.2" Could not open file "./merged/case.result0.3" ERRO...

Looks like Output File Cycle = 2 works not only for ElmerSolver but also ElmerSolver_mpi. I get case.resultn0 case.resultn1 where n = 0,1,2,3 for 4 processors as well as case.resultn0.pos case.resultn1.pos for binary files But say that between 0 and 1 you have chosen 0. Then you must not forget to r...

Good start of the week From what I understand Timestep Intervals(1) = 1000000 Output Intervals(1) = 0 Output File = "case.result" will yield a case.result file after the 1000000th time step However, our computer server facilities in Canada will abort our batch job when a maximum time allot...

Hi I just needed the normal to the surface at the boundary for plasma flux purposes but the problem is that ElmerSolver was bombing out at IF (ParentElement % BodyId == 1)THEN ........ after ParentElement => BoundaryElement % BoundaryInfo % Right or ParentElement => BoundaryElement % BoundaryInfo % ...

Hello once again I am using the command ElmerGrid 2 2 left -in right -unite -out merged where the mesh.boundary files under both folders left and rights have only one parent: from section A.4 of the Elmer manual pdf, every line in these files is of the form e1 bndry p1 0 type n1 ... nn Unfortunately...

Thanks for the suggestions but for plasma work, the electric field equations are coupled to the fluid flow equations. With two different meshes over the air region I would have to interpolate between them which would defeat the purpose of using already developed open source software like Elmer , Ope...
