error in parallel run
 

I run the case in serial scheme but when want to run in parallel it desn't perform.

Greetings Ehsan,

OK... I think you need to read once again some instructions on how to get help: http://www.cfd-online.com/Forums/ope...-get-help.html

Because from what you've provided, I can only guess that you're triggering a bug that has already been fixed in either OpenFOAM 2.1.1 and/or 2.1.x.

The two lines after the big "FOAM FATAL IO ERROR:" line should pretty much be self-explanatory, if you have access to the file it's pointing to, namely the file "0/R".

Best regards,
Bruno

hi
this is R folder.is there anything wrong with this?I only changed left patch to zeroGradient because this patch is changed between wall and surroundings.thank you for help.

Is file R used in Your case? If this file is not used in Your case, then You must remove it

hi.thanks.I used kOmegaSST and in walls it was set to kqrWallFunction.im not sure is this R related to that wall function?what folders are need to be in 0 folder for turbulency totally?
Thank you.

R - is Reynolds stress, predicted by k-omega sst model, it is not used in Your computation.

typical turbulent incompressible RAS case must have definition of initial and boundary conditions for next fields:
pressure - 0/p
velocity - 0/U
turbulent viscousity - 0/nut (for parametric RAS models)

Selected turbulence model introduces it's range of additional fields, for example:
kEpsilon - fields k and epsilon,
kOmega - fields k and omega,
SpalartAllmaras - fields k and nuTilde
RSTM - field R (reynolds stress tensor)
Choice of additional field is mutually exclusive

Selected additional fields determines contents of system/fvSchemes and system/fvSolution

thanks.my case is compressible.so for kOmegaSST model I only need to k and omega folders?right?then I should delete other folders related to turbulancy like R.am I right?

Yes, You are right. for compressible case you need mut instead of nut, mut=rho*nut, temperature field T, alphat - turbulent enthalpy diffusion coefficient
