[OpenFOAM] time stepping problem

iafpython · May 26, 2015, 13:43

Hi everyone!

When I use sonicFoam solver it throws me this message from a window

Warning: In /home/openfoam/OpenFOAM/ParaView-4.1.0/VTK/IO/Geometry/vtkOpenFOAMReader.cxx, line 4400
vtkOpenFOAMReaderPrivate (0x4d73350): Different time directories with the same time value 0.007 and 0.005 found. 0.005 will be ignored.

and others like that one, if anyone could help me to overcome this I would apreciate,

Igor

Hi Igor,

It is difficult to try and figure out what is going on with so little information given.

This looks like an error from ParaView? Sometimes it gets upset when you have weird folders in your case, which might appear if you have run the solver multiple times in your case folder. Perhaps you could let me know the names of all of the folders in your case folder? Eg: 0, constant, system etc

Regards,
Nicole

Hello Nicole!

iaf@iaf-Inspiron-5520:~/OpenFOAM/iaf-2.3.1/run/tutorials/compressible/sonicFoam/laminar/shockTube_100$ ls
0 0.002 0.004 0.006 0.org Allrun foam.foam
0.001 0.003 0.005 0.007 Allclean constant system

Those are the folders in my case (shockTube_100) ...0,002-0,003- are generated after the simulation.

Thank you very much for your concern.

Best Regards,

Igor

Hi Igor,

So your case is running? When exactly do you get the error message then?

Regards,
Nicole

Hello Nicole,

First; the message appears when you open the case that you already run before.
open paraview, then; open ConrolDict...

And, when you want to reproduce the simulation, in paraview with the button of going forward just one step at a time, then it also appears.

Hi Igor, have you perhaps run the solver more than once in that case folder and the first time it took 0.007s to solve and the next time 0.005s so they're might be a slight difference between the files that paraview is picking up? I would try just deleting all the 0.00.... etc files, just leave the 0 file and run the solver again on a clean case of that doesn't take too long. Maybe that might help. Paraview often has weird errors, for me it has often been something like that. Starting again with a clean case usually helps. But perhaps there is someone else on the forum who knows more than me.
