CFD Online Discussion Forums - Where to find information on dictionaries

Hello Vito,

thanks a lot for the reply! :)
I am not sure I understand what you mean though. If I search for "dynamicMeshDict" in my OpenFOAM installation folder, this is what I get:

Code:

mattia@replicant:~$ of230

mattia@replicant:~$ cd $WM_PROJECT_DIR

mattia@replicant:OpenFOAM-2.3.0$ pwd

/home/mattia/OpenFOAM/OpenFOAM-2.3.0

mattia@replicant:OpenFOAM-2.3.0$ find . -name "dynamicMeshDict"

The only file I thought might be what you were referring to is the last one, but I'm afraid it does not contain what I was looking for:

Code:

mattia@replicant:dynamicRefineFvMesh$ cat dynamicMeshDict

Did I misunderstand your suggestion?

Thanks again for your help :)
