Hello Bran,

in the release version of the wall model it is not possible to choose the height of the velocit ymapping point. Close to the wall u_tau is always calculated lower then DNS value.
Body force is firstly substracted and then added during the simulation step, so at the end the velocity is not influenced by the force.
If you need more help please write us at info@openlb.net
