Physics simulations can sometimes be unstable and it is always dependent on the parameters and settings of your project. In WaveMaker you have to be careful with the combination of specially these three parameters: - Resolution of the surface. - Speed propagation of the surface. - And the fixed time step size you set in your project settings. If you need to have a very high resolution surface, the speed propagation of the waves will be slower. But if you try to make it faster, a warning will come up telling you that higher values will make the surface unstable. As you can see, it is unstable. The first solution is to reduce resolution as much as you can. That will always be good for the efficiency of your whole project. After setting the minimum resolution, then select a wave propagation speed. If a warning comes up you will have to be careful. One solution is to make the fixed timestep smaller. You can set the fixed timestep size in the project settings, under Time. But this will affect not only the simulation of waveMaker but also the whole project, so be sure you understand what you are doing and I recommend not changing it. That is why we have a "substeps" parameter on each surface, allowing to locally increase the number of fixed timesteps each surface performs without modifying the whole project. More than one will make the simulation take more miliseconds of the frame time, but you will be able to increase the propagation speed without a warning. Be sure to keep the substeps to one or a very low value until you can reach the desired wave speed. So you have to choose between efficiency and high quality. I recommend chosing the lowest resolution and substepping, and not modifying the default project timestep. In fact it looks better with lower resolutions, you will have less noise in your waves."
