2d- fluid simulation with velocity field
Solving Navier Stokes numerically, figured out the workflow with the help of this paper by Jos Stam: https://pages.cs.wisc.edu/~chaol/data/cs777/stam-stable_fluids.pdf
This is a Java Project consisting of 3 classes. It produces a series of images that can be put together to a video.
The main class is FluidFlow.java, where one can do modifications to change the output.
-In the class head on can change image size, and various parameters. The boolean "fourier" should remain false, I didn't get it to work The boolean "viscosity" can be made true, but I only implemented a one-step numerical solution, so visc can't be set too high lest it explodes The boolean "obst" specifies wether we have an obstacle with boundary conditions
-In the constructor one can specify the initial state of the colors
-In the main method, one can specify the type of obstacle
-In the method "update" one can specify the force pattern disturbing the fluid
The other two classes handle Vector Fields and Scalar Fields respectively.
