Trouble with kappa lookup

cal25 · July 8, 2015, 16:28

I am attempting to use the turbulentTemperatureRadMixed boundary condition and would like to set kappa to a constant. I have set kappa to "lookup", kappaName to "kappa", and tried placing a volScalarField file named "kappa" in both my constants folder and my 0 folder. Regardless of where I put this file I will always get the following error:

Did not find field kappa on mesh tunnel patch tunnel_to_HX

tunnel is one of my domains and HX is my other.

Where am I supposed to define kappa when using the lookup option?

I also confronted the same trouble.
Does anyone know how to resolve this problem?

I think you would need to change the solver's code and create an IOobject in the object registry (similar to what's done in the creatFields.h file of most solvers).
