chtMultiRegionSimpleFoam Compilation Error
 
2 Attachment(s)
Hello,


I am trying to run chtMultiRegionSimpleFoam for my problem. I have created it's geometry and mesh in Salome. After that, I imported the UNV file in OpenFoam4 and Meshed it using IdeasUnvToFoam utility. It was successfully completed without errors.


My geometry consists of three solid regions. Hot_box, cold_box, and Rod.


both these boxes are connected using the Rod between them. And I am trying to simulate the heat transfer from the Hot_box to cold_box. The figure of the mesh and geometry is attached.


After modifying the case directories according to my problem, When I run the Allrun command it gives the following error.


Code:

Solving for solid region Hot_box

--> FOAM FATAL ERROR:
cannot be called for a calculatedFvPatchField
    on patch room of field h in file "/home/openfoam/run/heatTest/0/Hot_box/h"
    You are probably trying to solve for a field with a default boundary condition.

    From function Foam::tmp<Foam::Field<Type> > Foam::calculatedFvPatchField<Type>::gradientInternalCoeffs() const [with Type = double]
    in file fields/fvPatchFields/basic/calculated/calculatedFvPatchField.C at line 187.

FOAM aborting


I am unable to understand the error. Can someone help me out in this?


Thank you

Post the rest of your case, 0, system and constant. Mesh should be small enough to post.

Thank you so much for your reply.



I had some mistake in writing the dictionary file for one of my regions in system folder. After rectifying it, the simulation is now running.



Now i am doing post-processing in paraview.


Thank you
