Wave Generation - Relaxation Zone's Heads up

Asalih3d · February 2020

Hello guys

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

https://www.sciencedirect.com/science/article/pii/S0141118718303705

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?

Kind regards

Dear User,

thank you for your comment. As you mentioned already, all details for RZ setup can be found in Altomare et al. (2018). In the wiki in fact, it is already reported: "The performance of the relaxation zone technique to generate waves and to compensate wave reflection is is described in detailed in Altomare et al. (2018), where a step-by-step procedure to design properly the RZ is detailed."

Thank you both of you
