Hi all,

I'm studying about LBM, so I have a few questions while studying, So I'm asking here It could be a simple software problem.

I know that if LBM is used, flow analysis is performed with a stochastic distribution of particles. But since it is a particle, how can I calculate the hydrodynamic forces such as drag and lift?

Instead of multiplying the pressure change in contact with the wall by the speed, I'm talking about when there is no wall. Here, the absence of a wall means that the wall was treated as a boundary condition, but the wall does not exist in the post-processing process. However, the particles recognize the location as a wall and bounce back. It's a form

I have tried
export block and block data (pressure * nomal Velocity) in using PARAVIEW : but In my case, there are no blocks, only point data.

Can someone help!
thank you!
