I am doing muldirectional focused wave verification by reef3d,but It asymmetries along the direction of propagation.How to solve it? Last edited by kamath; April 27, 2022 at 07:36.

I mean I am doing a simulation of a muldirectional focused wave on a hill climb by reef3d,but the flow field is not right.It is not symmetrical along the centerline.How to solve the question?

That is a possible reason that the wave profile is not symmetric. I recommend that you run a test with flat bottom (constant water depth) first to see whether you get symmetric wave profile before you move on to the shoaling case.

Hi! I have done muldirectional focused wave propagation in an empty tank before,and the result is the same.

Hi, Here are the example control files for 3D focused waves, you can use them as reference for your setup

Hi!Are your velocity contour results symmetrical along the centerline?
