Khan: request help on LB programs

Hi Dear All,
I hope a lot of friends will work using LBM for flows around a circular cylinder. I find that it’s very difficult to get the clear pictures for vorticity contours like that flows around circular cylinders, i think they have many reasons like inlet/outlet boundary conditions, wall boundary conditions, grid size, relaxation time parameter and like low viscosity. Those that they have already such an experience and then they overcome and now they have a code for good stable results. I request to every one that if they have such an experience and if they share some good points for those working on LBM for flows around circular cylinder, it will be really appretiated.
Thanks in advance my friends.

Hi Dear All,
Can any one have a code for calculating streamlines for two circular cylinders in a tandem arrangement.
Any help can be really appreciated and thanks in advance.

Hi,
I need to ask the lbmethod.org that how to post a picture on this side for discussion.
Thanks in advance.
