Windows-Elmer-LoadMesh ...does not exist????

Windows, FreeCAD 0.20.2, Using ELMER and GMSH…Get error message in Solver Control:

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

Solver Control Working Directory: C:\temp-sys\fempoimp5yu Contents of this directory:

case.sif
ELMERSOLVER_STARTINFO
mesh.unv

I’ve edited case.sif line starting with Mesh in various ways to try to get through…but no joy, always same error message.
Original case.sif file:

   Check Keywords "Warn"

   Header
     Mesh DB "."
   End

   Solver 1...

I’ve even done some manual editing of the Mesh line and tried:
Mesh DB “c:/temp-sys/fempoimp5yu”
Mesh DB “c:/temp-sys/fempoimp5yu” “mesh”
Mesh DB “c:/temp-sys/fempoimp5yu” “mesh.unv”
Mesh DB “c:/temp-sys/fempoimp5yu/mesh.unv”

I’ve even seen the error as: ERROR:: LoadMesh: Requested mesh > c:/temp-sys/fempoimp5yu/mesh.unv< does not exist!

Oh, in case you’ve not yet figured it out, I am very much a noobie…thanks in advance!

Please add your full About info to OP

Hello,

I ran one of the Elmer FEM examples in Freecad on Windows yesterday and experienced the same issue. I downloaded and installed the latest Elmer version and the Elmer FEM example in Freecad ran properly to completion.

Apparently ElmerGrid had a bug that only affected the Windows version. Reinstalling Elmer using a Windows installer date 4 May 2023 or newer will fix the issue.
