Hello,
How would I impose a non-zero internal velocity boundary? For example, if I wanted to make the cylinder in the cylinder2d example have a fixed rotational surface velocity. Is there currently a straightforward way to do this in OpenLB?
Thanks.
At the current stage, a slip velocity on the boundary is possible for straight boundaries only. Bounce-back boundary nodes, as the ones used in the cylinder2d example, are straightforward full-way bounce-back and can be used for no-slip walls only.
