Hi everyone!
I'm a new user of OpenFOAM, so I'm sorry if my questions are simple.

What I'm trying to do is to simulate a spray injected in a chamber with turbulent flow inside and no chemical reactions at all. I'm using sprayFoam solver.

So my questions are:
1) To switch off the chemical reactions I wrote "active no" in constant/combustionProperties, but is this enough or do I need to write "chemistry off" too in constant/chemistryProperties?

2)In constant/sprayCloudProperties I have to insert T0, rho0 and Cp0, but I only know the T0 for my liquid and its injection pressure. Is there a way to make OpenFOAM calculate rho0 and Cp0 on its own? Or do I have to look for those data and insert them manually?

3)Is there a way I can extract the data about the spray penetration and timesteps from the output file and write them down somewhere else?

Thank you in advance and again sorry if these are simple questions.
