Dear JC,

</div>
<div>I would take about 10 very small timesteps.</div>

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

<div>Howdy Nek's,<br>
<br>
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?<br>
<br>
Best regards,<br>
