Hello everyone!rnI have a simple 3D Poiseuille flow with pressure inflow and outflow boundary conditions. I need to impose an additional force term to a set of the cells inside the domain. The term is simply added to the post-collision distributions: f* = f* + a, where a is a force term. What would be the best way to implement this with OpenLB? Thank you!
Hi Wolf,rnrnThere is already a model to include external forces inplemeted. Please look at the “”forcedPoiseuille”” example. You can also add any term to f*. Just like rn lattice.get(iX,iY)[iPop] += a;rnrnBut mind that in OpenLB f = f(standard)-f^eq(1,0)!rnrnBest regardsrnMathias
