wallHeatFlux with laminar flow

PositronCascade · November 16, 2017, 14:52

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.
