I want to use Elmer FEM for the simulation of solidification processes in a foundry. I use the system for two month now and it seems to work fine for small problems.
Recently I tried a longer running simulation (25.000 Timesteps) and encountered serveral problems:
1.) I tried to log the timesteps in a file "zeit.dat"
Code: Select all
Solver 2
Exec Solver = After Timestep
Exec Interval = 1
Equation = String SaveScalars
Procedure = File "SaveData" "SaveScalars"
Filename = File "zeit.dat"
Variable 1 = String Time
End
5.000000000000E+000
2.500000000000E+000
5.000000000000E+000
1.000000000000E+001
7.500000000000E+000
1.000000000000E+001
1.500000000000E+001
1.250000000000E+001
1.500000000000E+001
2.000000000000E+001
1.750000000000E+001
2.000000000000E+001
2.500000000000E+001
2.250000000000E+001
3.280000000000E+002
2.500000000000E+001
3.000000000000E+001
2.750000000000E+001
3.000000000000E+001
3.500000000000E+001
3.250000000000E+001
3.500000000000E+001
What did I do wrong?
2.) I tried to export the solution to vtk to post process it in ParaView.
Code: Select all
Solver 3
Exec Solver = After Timestep
Exec Interval = 1
Equation = Result Output
Output Format = Vtu
Output File Name = ergebnis_export_vtk ! Name des exportieten Ergebnisfiles
Procedure = "ResultOutputSolve" "ResultOutputSolver"
Show Variables = Logical True ! Gibt eine Uebersicht, welche Exportvariablen moeglich sind
End
I was not able to load them into ParaView correctly. All I got where the first 10000 steps.
Is it possible to use more numbers at the end of the file name?
3.) I tried to log temperature results during the simulation. I used a code snippet I found in this forum.
Code: Select all
Solver 4
Exec Solver = After Timestep
Equation = SaveScalars
Procedure = "SaveData" "SaveScalars"
Save Points = 7
Variable 1 = Displacement
Filename = "DiskData.dat"
End
timestep 1, displacement at node nr 7, displacement at node nummer 8, ...
timestep 2, displacement at node nr 7, displacement at node nummer 8, ...
and so on.
Is this possible?
Thank you.
Have a nice weekend.
