Density #4

Closed BenJury22 closed 1 month ago

BenJury22 commented 2 months ago

Create a function which can continuously track the density at all points in the fluid. This function will be used to find the pressure force exerted on each particle to make particles move from areas of high density to areas of low density.

The density function we're using at the moment has some issues so I want to create a colourmap to track the density of every point on the surface (not just at the particles) to better understand these issues.

I fixed the density issue but didn't make the colour map because it would be too memory intensive (and i couldn't figure out how to do it)
