Accelerated Body Motion Simulation

reza1111 · May 27, 2013, 09:49

Hi,

We know the motion of body with a constant velocity in a fluid can be simulated by fixing the body and imposing the velocity in B.C.
For calculating the forces around the body (Lift&Drag) can we do this in a body with variable velocity ( with acceleration)?
for example for calculating the forces (Lift&Drag) around the body with sinusoidal motion can we fix the body and impose a sinusodial motion in B.C
Why?

Best Regards

Any ideas?

Yes, you can do that in unsteady mode.
