Wave Generation - Relaxation Zone's Heads up
I have spent a few hours, trying to figure out how to actually determine how to set the constants psi and beta, when using this formulation. Finally I figured out how, and a description can be found in this paper:
Improved relaxation zone method in SPH-based model for coastal engineering applications
4.2.2. Design of RZ for wave generation
This is not apparent from the wiki on Github (as far as I could find) and I think someone with more knowledge than me should add this to the wiki, or atleast the reference. Just posting here as a heads up.
I am still unsure of how to confirm that the values for psi and beta give the correct physical results, but I guess one just has to compare the SPH free surface with the height and period one has specified analytically?
