Hii all,

i have been trying to run my openfoam case in parallel, I have managed to do that with the following code. I am actually getting results and they look good. I wanted to double check the code to make sure that there is no error/mistake before i run all of my cases.

##################

mkdir 0

cp constant/turbulenceProperties_sst constant/turbulenceProperties

blockMesh

decomposePar -force -copyZero

mpirun -np 16 snappyHexMesh -parallel -overwrite

reconstructParMesh -constant -mergeTol 1E-06

rm -rf processor*

extrudeMesh

checkMesh

rm -fr 0

cp -r 0.org 0

setFields

decomposePar

mpirun -np 16 olaFlow -parallel

touch full.foam

##########

Did i do something terrible ? Please help

Paul

I think it is better to add
Code:
reconstructPar -constant
after the
Code:
reconstructParMesh  -constant -mergeTol 1E-06
command line.
