How to export pressure for a simulation
Your code is really useful. Thank you very much for your contribution. I encountered a problem while using the program. I noticed that when using the gridToVTK function to output the simulation results, there was a line of commented code: # cellData={"pressure": pressure}, but there seemed to be no pressure parameter defined in all the codes. How can I export pressure for a simulation？
Hi, in LBM we don't calculate pressure directly, we use EOS to estimate pressure from density, so if you have density rho, you can calculate pressure from there :-)

Yes 😊

Does EOS refer to equations such as p=ρRT for ideal gases?
