Dear Sir

THanks for ur reply. I think I'm not clear with my question. I have to input this value of lift or we can say I need to apply some forces on a body as input, condition. Like we apply velocity at inlet, I need to apply force at particular point in ANSYS FLUENT.

dear Bassim my doubts are in ls fluent (cfd analysis) not on ls dyna
