PisoFoam and Gravitation
I'm new in OpenFOAM and so I do not have so much experience with changing code etc.
I do have a problem with PisoFoam. I'd like to use the buoyantPressure at the walls but I get the following error message:
I think, there is a problem with the gravitation. I do have a file in constant/g which stands for the gravitation.
I saw the thread but I do not really know what to change: http://www.cfd-online.com/Forums/ope...behaviour.html
Thank you in advance for your help. Have a nice day.
The problem is running on OpenFOAM 2.0.1
pisoFoam does not account for the gravity, so no gravitational vector is defined when you run it. The buoyantPressure condition is equivalent to zeroGradient, if g = 0.
You might want to take a look at solvers involving buoyancy (heatTransfer directory).
thanks for this information. I'll try with another solver.
