Add the volumetric force source terms

General
1

Hello All,

I tried to simulate the wind turbine wakes by actuator line method. But, how can I add the volumetric force source terms to N-S equations? And, where can I find and change the turbulent flows model in PyFR?

Thank you for your help.

Regards,
Edmund

Source terms can be added using the [solver-source-terms] directive in the .ini file. Further details can be found in the user guide: User Guide — Documentation

Being designed for ILES, PyFR does not make use of a turbulence model.

Hi Freddie,

Sorry for bothering you again. When I imported .msh to PyFR, there is an error. In the 2D model, the KeyError is (x1,x2) and in the 3D model, the KeyError is (x1,x2,x3). Whether this represents the coordinates of the node? Do you have any idea about it?
Thank you for your help again.

This is indicative of a bad mesh file with either unpaired faces or incorrectly tagged boundaries.
