Hey,

As far as I understand (correct me if I am wrong) the solution time for incompressible LBM is greater than for FDM/FVM/FEM, assuming similar errors.

Will the solution time be similar for the two methods if the FDM/FVM/FEM method is using a pseudo-transient approach for the solution of the poisson equation for pressure?

Cheers!
