Post-process of a decomposed case

Hi everybody,

I'm trying to post-process a decomposed case. I've tried two ways but no one worked.

I tried to postprocess the case using the parafoam -builtin command, but when i set the case type to "decomposed" I receive the following error:

Code:

ERROR: In /usr/local/OpenFOAM/ThirdParty-2.1.1/ParaView-3.12.0/VTK/Filtering/vtkExecutive.cxx, line 756

vtkPVCompositeDataPipeline (0xd920160): Algorithm vtkPOpenFOAMReader(0xd90eba0) returned failure for request: vtkInformation (0xd8f9540)

  Debug: Off

  Modified Time: 71379

  Reference Count: 1

  Registered Events: (none)

  Request: REQUEST_INFORMATION

  FORWARD_DIRECTION: 0

  ALGORITHM_AFTER_FORWARD: 1

-------------------------------------------------------------------------------------

I tried then to reconstruct the case. But reconstructPar gives me this error.

Code:

Cannot find file "points" in directory "polyMesh" in times 0 down to constant

In the 0 folder I have a polyMesh folder created by refineMesh that contain a cellmap.gz file, but all the points.gz faces.gz owner.gz etc files are in constant/polymesh folder. Anyway I tried both renaming the 0/polymesh folder and copying the constant/polymesh folder in 0/polymesh folder, but the error remains there.

How can I postprocess this case? And why I'm getting these errors?

Hello,

I had also the same error massage:
Create time

Quote:

Create mesh for time = 0

--> FOAM FATAL ERROR:
Cannot find file "points" in directory "polyMesh" in times 0 down to constant

From function Time::findInstance(const fileName&, const word&, const IOobject::readOption, const word&)
in file db/Time/findInstance.C at line 188.

FOAM exiting

I just use the folder 0, constant and system and created a new case with them.
I used decomposePar and after that I realized that there is constant - folder in each processor-folder.
In the original case (where I get the error massage) were no constant - folder in the processor-folder any more.
So I just copied the constant folder from the processor-folder from my new case to the old case and tried reconstructPar again. And it worked :)

Maybe this could help you too

Regards

Thank you. i don't need it anymore, but someone maybe does.

Thank you very much. bye

really appreciate ! it helps me alot

In my case, I had downloaded the simulation from the cluster to my local machine but one of the processor* folders did not contain the files inside its constant folder.

Just complete the processor* folder with the cluster's processor*/constant folder or decompose the case and copy-paste the constant folder.
