Re: Setting Boundary Values
Hi Sumit,
the dependency of the timesteo size on these parameters is intrisic to the lattice Boltzmann method. There is no function to change the step size without affecting the spatial discretization and / or latticeU.
You just can look at the dependenccies in the LBconverter and maybe find a configuration that is suited for you. E.g. a smaller charU should result in larger physical timesteps, so maybe decreasing charU and setting x*converter.getLatticeU() in the CirclePoiseuille?
