<font size="-1">Hi, <br>
<br>
In an simulation with the LowMach number formulation <br>
I need to compute the term :<br>
Laplacian(U) + 1/3 grad ( div(U) ) <br>
<br>
Is it stored somewhere ( BFX,BFY,BFZ ??? )?<br>
<br>
Moreover, since i need it anyway during postprocessing,<br>
which is the most efficient way to extract it? <br>
<br>
Thank you.<br>
