Hi every one
I want to simulate acceleration of body in air
I must use dynamic mesh. I used macro C G Motion for motion of an airfoil.
I set mesh of boundary layer in rigid body motion that it moves with the airfoil.
fluent computes the velocity on the airfoil at each time step. it is wrong . I computed velocity with equation v=at+v0
and acceleration is linearly. I set mesh of boundary layer in rigid body Is it wrong?
