[Nek5000-users] Compute Pressure from a given velocity field

[nek5000-users at lists.mcs.anl.gov]

Dear JC,

I would take about 10 very small timesteps.

The inertia should keep the flow from changing;  going to step 10 will get you past peculiarities of Nek's start-up
process for the BDFk/EXTk start-up procedure.

Howdy Nek's,

I was wondering if anyone could explain to me how to compute the pressure from a given velocity field? Say I have a blah0.f00001 field containing only vx,vy, and vz. Once I have loaded it in userchk in postprocess mode, is there anyway I can compute the corresponding pressure field?

Best regards,
JC
