Hi, I'd like to try the tutorial of PDRFoam solver. I go in the correct path and I launch the blockMesh command. Now the mesh is complete and I can launch the solver typing PDRFoam. Unfortunately the case gets the error:

--> FOAM FATAL IO ERROR:
cannot find file

file: /home/francesco/OpenFOAM/francesco-2.1.0/run/tutorials/combustion/PDRFoam/flamePropagationWithObstacles/constant/betav at line 0.

From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 73.

FOAM exiting

The solution seems simple by copying the file <<betav>> in the <<costant>> folder, but after this kind of error occurs:

/home/francesco/Scrivania/tutorials/combustion/PDRFoam/flamePropagationWithObstacles/0/betav

What's wrong? Another question is: what kind of files are <<Allrun>> and <<Allclean>>? Do I have to use them?
Thanks a lot,
best regards
