Hi,
I am beginner of OpenLB. Anyone can help me with the following problem.
How to extract the pressure data on the specific lattice (iX,iY) in one example of the release olb-0.6- “poiseuille2d”,
I suppose using the method of lattice.get(iX,iY).computeRhoU( rho,u) which obtain the density, however, all the data is positive which is wrong based on the analysis result. any suggestions on getting the pressure value?
many thanks!
