I am new to openFoam and running a case to learn parallel processing in openFoam.


After decomposePar, it devide the problem amongst the processors.


then when the command: mpirun -np 4 icoFoam -parallel > log &


is applying it does not run the problem and gives error as per log file.


thanks in advance
