Hello all.....

i have written udf for wing sweeping. The equation gives rotational velocity in radian per second. fluent is printing the right values that correspond to the code and at the same time , zone motion also shows me correct sweeping motion of wing but when i write the same code in terms of dimensionless variables, the fluent although, still prints me the values that corresponds well with the code but i dont see any motion of airfoil in zone motion preview. My question is that, is it necessary to write equation in dimensional variables for fluent, to replicate the motion as desired by the equations?
