Hi all
I need to access from my main solver the function nuTilda() in the class spalartAllmaras for compressible RAS turbulence model.So i did the same as forthe function mut(): i added it to the file turbulenceModel.H recompile the library libcompressibleturbulence, then add the line in my solver :
VolScalarField nuTilda(turbulence->nuTilda());
I didn't get the expected results.
Any idea?

Hi,

1. OpenFOAM version?
2. What do you expect to get?
3. Why mess with turbulenceModel.H instead of creating child class of SpalartAllmaras and use it to access nuTilda_ field?

Hi,

thanks for your reactivity. I found a solution with the following line
volscalarField nuTilda = mesh.lookupObject<volScalarField>("nuTilda");

Please, how do you create the child class so as one can access the nuTilda field in the main solver as well as modify the field?

Cheers
