Resulting pressure on obstacle

[BimwerxNZ]

Excellent work! Thanks for sharing! Is it possible to determine the resulting pressure on the obstacle?

The pressure is not computed by the code, but pressure can be computed starting from density (which is computed and displayed in this project). See for example this for some details: https://physics.stackexchange.com/questions/251702/calculating-pressure-in-lattice-boltzman-equation
or here at the end of page 3: https://homepages.abdn.ac.uk/jderksen/pages/lbm/ln02_lb.pdf

I'm quite sure that the links I provided on the project blog entry have more info on this.

This might be a good addition to the project, so I'll leave this open... although for display purposes it's not so useful, since it's only a multiplication with a constant.
