<div dir="auto">I performed some simulations around a plunging flat plate.<br></div>
<div dir="auto">I have to compute the volume integral over a choosen domain (a rectangle around the body with a fixed geometrical dimension) of the eulerian time derivative of the vorticity field multiplied by the local position vector components. I found a subroutine to compute the vorticity. How should I compute vorticity at the previous timestep? And how can I perform the integrations? <br><br></div>
