  • Inertial Forces / River Problem

    Hello all,

    I have attached a few images to give you an idea of what I am trying to do. It's been almost a year since I have done anything major in Phoenix FD so I'm still catching up on all the new features.

    What I am trying to create is a river with a oil slick that runs down and is being recovered (this will loop eventually). I may be going about this all wrong so if it looks like it please let me know a better way.

    The Problem
    Initially I had the entire river as the simulation, but I was not getting the best results (I'm super rusty) so I am trying the ship method and hoping to apply it to the individual parts of the objects in the river (this may not work). I have no idea if using the ocean texture (displacement) with different simulations for every object in the water is the best way to do this. However, I have been getting issues with the initial fill up losing water and then having the simulator grid affecting the water more than the object in the container. Is there something I need to check to make sure the container is not applying any force to the water? I followed the ship tutorial and could not find a reason my simulation was acting different.

    the reason for the visible borders is the low resolution, it's relatively easy to decrease the border visibility by adjusting the ocean level in the rendering panel (you can use non integer values). nevertheless you will need displacement waves to hide it completely, it's almost impossible to have pure flat surface in animation.

      will increasing the resolution also eliminate waves being generated by the boarders of the simulator? I planned to have displacement enabled, but was trying to solve the issue with the simulator boarder so I turned it off to illustrate my issue with more clarity. I realize the displacement will hide it in the end, but it becomes problematic when I add spray and foam because the simulators boarders are creating enough of a stir for those items to be generated along the boarder. I will run some tests tomorrow with increased resolution and let you know how it goes. Thank you!

        the simulator borders create foam? increase the threshold, this will prevent the birth at places where is not desired.
