First I started by spending quite a bit of time refreshing myself on fluid dynamics and getting somewhat overwhelmed. I had to remind myself that for the purposes of this I Don’t really need to bother 100% accurately simulate everything in a fluid, not even close.
As stated in the project description now, I have decided to focus this project on compressible flows (really just simulating gases), as that seems like a better place to start than working with liquids and solutions in liquids (but I do want to end up there eventually!).
The first while here will be spent just getting pseudo ‘gases’ flowing through a grid. All that I threw together in the first hour or so was effectively a grid where values are diffused from one cell to another. What is shown below is a very simple & temporary visual display made via unity gizmos of that happening. I’ll be throwing together a shader to properly display it promptly (which will likely be made up of recycled code from my previous fluid simulation, as this is pretty much the same thing lmao).
