obtainiing and stroing fvScalarMatrix from Spalart Allmaras OpenFoam

Hi All
I am trying to get the fvScalarMatrix nuTildaEqn value from the Spalart-Allmaras turbulence model and print it in main simpleFOAM.C program.

I have tried to access it using lookupobject but with no luck.
Can any body suggest how i can extract the value of nuTildaEqn matrix and store it in some variable name in the main simpleFOAM application rather than solving it in turbulence model.

You can run openFoam in the gdbOF debugger (see https://openfoamwiki.net/index.php/Contrib_gdbOF) and use predefined macros to extract the matrix.

Good luck, Domenico.
