Question
I am trying to create a epotFoam solver from icoFoam. After creating the files, when I am trying to run the case, it is showing the following error:

 FOAM FATAL IO ERROR:
keyword PotE is undefined in dictionary/fvSolution.solvers from line 22 to line 52.
From function const Foam::dictionary& Foam::dictionary::subDict(const Foam::word&) const in file db/dictionary/dictionary.C at line 701.
FOAM exiting

Can some one pls help me with this error.

Answers:

Hi,
Is any term "PotE" term is used in the equation?
If so the the numerical scheme to solve the term should be specified in the fvSolution file.
To get a clear idea I need to check the solver. If possible send it to cfdfossee@gmail.com

Can you tell me how you solved it? I am facing the same issue.

in the fvSolution file in system directory, add the term PotE like the rest of the variables in the file as shown below:

PotE
{
solver PCG;
preconditioner DIC;
tolerance 1e-07;
relTol 0.01;
}

Use the solver and preconditioner accordingly. This will solve the problem

Hi,
I did what you said about this issue, but I got the same error.

The numerical scheme has to be added for PotE function, in the fvSolution file
