Applying a spatially varying body force term

pandamaster9 · April 26, 2022, 05:40

Hello all,
I have been working on the periodic hill problem using Incompressible RANS. I know there is a direct way to implement a body force using BODY_FORCE = (bx,by,bz) in the config file.

However, for my purposes I want to learn how to implement such a body force that is spatially varying throughout the flow field i.e. b(x,y,z) as a vector field, in my su2 config file for the simulation.

Thank you

Hi,
Have a look at this discussion: Adding a configuration option to read a file
We do not have a built-in way to do that, you'd need to write some code.
