Hi all

I want to calculate the Nusslet number in ParaView. When I calculate the inner product to normals and grad(T), it gives me this error:

ERROR: In /home/OpenFOAM/ThirdParty-7/ParaView-5.6.0/VTK/Common/Misc/vtkFunctionParser.cxx, line 1244
vtkFunctionParser (0x5612add94000): Syntax error: expecting a variable name;  see position 0
Do you know how to solve it?

Also, it seems that wallHeatFlux does not work in my solver: rheoHeatFoam.
Do you know any other way to calculate that?

Thank you!
