Hello everyone. I try to use wallHeatFlux utility on OpenFOAM 5 for laminar case. However, I get this error even I have turbulenceProperties file in the constant folder:

Code:
Unable to find compressible turbulence model in the database
May it be a bug or what am I missing?

Thanks.

Hi.

The message is telling you that the postProcess utility has not information about the turbulence model use in simulation.

You can run the postProcess with the solver:

<your_solver> -postProcess -func wallHeatFlux -region <region_name>

Hallo Foamers,

I am a little confused about functionObjects. I wrote in controlDict

Code:
functions
{
#includeFunc wallHeatFlux(region=heater)
}
and run
Code:
chtMultiRegionSimpleFoam -postProcess
or
Code:
chtMultiRegionSimpleFoam -postProcess -func wallHeatFlux -region heater
the terminal reported
Code:
Cannot find functionObjects file wallHeatFlux
Without any input in "functions{}" in controlDict, I ran in the terminal
Code:
wallHeatFlux -region heater
it works fine.

Why the former two command do not work please?

Thank you very much in advance!

Best regards,
sitajeje

Hello,

chtMultiRegionSimpleFoam does not offer wallHeatFlux function. you need to use wallHeatFlux option of chtMultiRegionFoam.
