Please can anyone help me with refinement for generating your wave. I am trying to simulate a first order wave with amplitude of 0.1m and length 5 mt. The total domain is 75X10X1. y axis forms the direction of amplitude. I have used a block of height 0.3 mts to refine the free surface. The mesh sizes in x and z direction is 0.0625(5/80) and y axis is 0.01 (0.2/20). I am getting a good comparison of pressure and velocity. My concern is the total cell count is very high. I am a wary because of this. When I will be working with ship wave interactions the total mesh can be too high, increasing the time. Also if the wave is so sensitive to mesh size, even for a small of amplitude or wavelength would require remeshing.
Could you please share your knowledge on wave simulation please?

Thanks
