Questions Regarding Turbomachinery and Compressible Module

[AndrewH]

Hello,

For the turbomachinery module, the rel_velocity and rel_pressure is output with the module, however are these variable necessary for the computation for the module? Code_Saturne uses an absolute/relative formatulation with the mass flux relative which means that the N-S equations shouldn't depend on a relative velocity or pressure. Is it possible to turn off these variable in order to minimize result files size? I have search through the source code, but for the life of me, I can't find them at all! They don't seem to controlled by the GUI or the cs_user files, and don't appear as defined variables in the listing or setup.log files.

Additionally for the compressible module, is turbulent Prandtl number defined as 1.0 by default from the base algorithm? It appears other modules redefine it as 0.7.

Thank you,
Andrew

Hello Andrew,

This extra postprocessing output is generated through src/base/dvvpst.f90. Not a user subroutine, but I'm not sure there is another way of deactivating the extra output than editing this... For the log files, I need to check.

Yvan
