field function STAR CCM+
 

Hi all
I did a stationary simulation and a rigid body motion simulation of the overtaking process in Star CCM+ so now I have to compare the results obtained. For this reason I tried to create, for stationary simulation, a new vector field function, relative velocity, that is, the vector velocity at which I subtract 10 m/s(the velocity of the moving car) along the X-direction(the direction of the motion).
please could anyone help me?
many thanks
