PotentialFoam Problems...
 

Hi all,
I'm doing a study on a submarine in deep water,
but I have a problem when I star with doing a potentialFoam -writep:
--> FOAM FATAL ERROR:
No valid model for viscous stress calculation.

From function forces::devRhoReff()
in file forces/forces.C at line 113.

FOAM exiting

Is someone have an idea of where it's coming from?

Thanks a lot!!

Maybe it's too late for you..
.. it should because of the "force" function in your controlDict, it will use viscous stress to calculate the force..
so just commend it off when using potentialFoam..

potentialFoam has an option -noFunctionObjects that overrides the function subdictionary of controlDict

total pressure
 

Hello everyone ,

Please let me know how to calculate the total pressure field (= static p + dynamic p) in case of potentialFoam.
i used potentialFoam -writep.

i have a doubt if p is actually p or something else.

Thanks in Advance,
antony
