Dear all, since I'm doing s
since I'm doing some testing of a modified turbulence model based upon the LRR implementation, I'd like to solve an additional equation for a tensor field giving me an idea about its quality - this field should be a copy of R_.
I browsed all the messages posted here, but, unfortunately, cannot find a solution of my problem.
First of all, I defined a new 'volTensorField' in my .H-File I named 'HELP1',
tmp<voltensorfield> HELP1() const
which is set to a fixed set of values in .C afterwards:
To solve this, I copy the field values of R_ onto HELP1_ and define the additional equation as follwing:
HELP1_ = R_;
where 'P' has the correct dimensions. All the fvSchemes and other input-files are set, compilation is done without any messages and the code runs properly (I'm using turbFoam).
When I add another term on the left- or right-hand-side of 'HELP1Eqn' - i.e. + fvm::div(phi_, HELP1_) - I get the message from Foam
--> FOAM FATAL ERROR : gradientInternalCoeffs cannot be called for a calculatedFvPatchField.
You are probably trying to solve for a field with a calculated or default boundary conditions.
My question now: what's wrong here? Where is something missing? Do I have to modify an argument list?
This might be a stupid question - my last C++-course at uni is years ago - but I wouldn't mind some useful hints...
Thanks in advance,
The problem is that you have n
The problem is that you have not set any boundary conditions for HELP1_ and have let them default to calculatedFvPatchField which of course you cannot use in a transport equation. You could either read HELP1_ and set the BCs in the file or obtain the BC types from R_.
Thanks Henry! After setting
After setting 'MUST_READ' to HELP1_ all works fine.
