Ok, this is a setter function for a legacy-style BC (i.e. this won’t work on GPUs. I recommend writing all new models in the new “operator” style. You can check out e.g. the local/interpolated velocity/pressure BCs and the user guide FAQ for an introduction. The code will also be much more compact).
Did you already implement the BoundaryStreamPostProcessorGenerator2D “generator” and its post processor?
What is your specific question?
