Reply To: Analysis of custom models
What do you mean by “the simulation didn’t run”? Which error / problem did you get? The example case on its own should be a good choice for a starting point in your case.
You can visualize streamlines in ParaView using the “Stream Tracer” filter on the velocity field produced by OpenLB. Similarly you should be able to compute the drag there (although OpenLB includes a drag/lift computation functor, this is used by e.g. the cylinder3d example case).
