decomposeParDict errors when deleted
 
I'm not running my case in parallel, why does my meshing crash when I erased the file?

Don't know why but sHM checks that file anyway so you need to leave that where it is.

Can you copy your error message here ?

Code:

--> FOAM FATAL IO ERROR:
cannot open file

file: /home/ubuntu/Desktop/condivisa/8_cilindro/system/decomposeParDict at line 0.

    From function regIOobject::readStream()
    in file db/regIOobject/regIOobjectRead.C at line 87.

FOAM exiting


This is mine, that is what you get when you do not have any decomposeParDict within you system folder.

Which utility are you trying to run here?

lovecraft22 April 4, 2012 07:57

sappyHexMesh

could this in any way be related to my other post where I stated that you cannot have more than two SHM instances running at the same time?

alberto April 5, 2012 11:54

This is just because snappyHexMesh meshes on multiple processors/cores.

mihaipruna April 5, 2012 13:07

I see...does that apply to solvers as well?

alberto April 5, 2012 14:31

No. Solvers and other utilities in general do not require a decomposeParDict.
