Hello everyone.

I ran the attached .sif file and got the error below. Please let me know if anyone can help me understand.

ERROR:: LoadMesh: Requested mesh > . /ring_ext < does not exist!

Thank you in advance.

In
Header
CHECK KEYWORDS Warn
Mesh DB "." "ring_ext"
Include Path ""
Results Directory "."
End

you told it the the mesh is in a sub directory called ring_ext of you current working directory but it doesn't exist

Thanks for the reply!

ring_ext.geo is converted to an elmer-like mesh using netgen,
ring_ext and inserted it into the current directory under the name ring_ext.
However, the following error was output
ERROR:: LoadInputFile: There are no Solvers in the system!
There is a Solver entry in ring_ext.sif, but an error is output.
How can I resolve this error?

Thank you in advance.

I did not get that error. You can see in the previous post picture doesexist that the job is running

Thanks for the reply!

I was able to execute it!
However, I got the following error output
ERROR:: IterSolve: Numerical Error: Too many iterations were needed.

It says that if the number of iterations exceeds 2000000 times, an error is output.

Thank you in advance.

You will have to post your mesh, I was testing with a mase up one of my own.

Please download from the github repository as the file is large.

https://github.com/Poraemonn/ElmerGUI

The mesh is ring_ext.geo converted to a mesh for elmer with netgen in a folder called ring_ext.

Thank you for your cooperation.

The other solvers are converging well. The WhitneyAVSolver is not, I have tried all of the normal modifications I know, but no results. The mesh looks good. I am not the expert on WhitneyAVSolver.

There was an important note in the sif
! Please note that for versions of ELMER FEM after 4 August 2019, "Relative Reluctivity (3,3)" should be changed to "Reluctivity (3,3)"
also needed to add jfix to the BCs

I was able to get a solution with this geo and sif file
the geo reduces the mesh size so that the mumps solver could be used, my system is 8GB Ram, more ram would allow for bigger models

Thanks for the reply!

I had overlooked the points you pointed out.

I am currently preparing to download mumps solver.
I will give it a try when I can download it.

Thank you very much.
