Hi! First of all I wanted to thank you for this very extensive benchmark, it's timely and super relevant to the ML for science community. I have a question regarding the implementation of the incompressible Navier-Stokes flow equations in pdebench/data_gen/src/sim_ns_incomp_2d.py. Could you please clarify which version of the equations is implemented there? Maybe I've missed something, but the pressure field is missing and it seems that the particles variable stands for the density field which is assumed to be constant for the incompressible version (?). Is the version implemented here the one described in the paper's appendix D.6, (eq. 18-19)?
Many thanks!
