Default Unsteady Flow waveform
Vidya Raja
Posts: n/a

I'm doing an unsteady flow simulation in Fluent. I have an inlet velocity wave described by an offset sine wave. I don't see the waveform on any of the velocity vector or pressure contour or any of the post processed plots. Is there any way I can get the waveform to be plotted on the velocity vector, pressure contour, etc plots? Is there any additional code or something to get it plotted?

Also, my simulation is running very slow. There are about 124,000 nodes in my geometry. Is there any way that the simulation can be sped up? If I increase the time step size, the solution doesn't converge and so I'm forced to give a time step size of the order of 1e-5.
