Why "keyword PISO is undefined"

BenXiaoDou · March 13, 2016, 08:48

Hello,
I am really new to OpenFOAM. After installing, I tried to run the cylinder case in tutorials/basic/potentialFoam/cylinder. The blockMesh part went well, but after icoMesh command, the terminal showed:

Create time

Create mesh for time = 0

--> FOAM FATAL IO ERROR:
keyword PISO is undefined in dictionary "/home/xie/OpenFOAM/xie-3.0.1/run/tutorials/basic/potentialFoam/cylinder/system/fvSolution"

file: /home/xie/OpenFOAM/xie-3.0.1/run/tutorials/basic/potentialFoam/cylinder/system/fvSolution from line 22 to line 41.

From function dictionary::subDict(const word& keyword) const
in file db/dictionary/dictionary.C at line 648.

FOAM exiting

I have no idea why this is happening. I would appreciate any help.

PS: My Ubuntu are totally newly installed. No software has been installed before OpenFOAM. Also, the case cavity went well without any problem. I do not understand why cylinder case is different.
