Reply To: Extract velocity, pressure, and density data on lattices without interpolation
Well I’m not an expert for file formats and csv, if it is not much data it is probably the easiest solution to use the c++ iostream functionalities for creating your csv file.
You may check out the computeU/ computeRho methods from the “Cell” class for velocity/ density. If you want to compute the pressure like that, you need to compute it “by hand” using c_s^2 * rho.
