Pressure Contours#

Pressure contours = {yes | no}

Description / Usage#

The hydrodynamic pressure is normally a field variable within Goma; however, it is often interpolated in finite element space with discontinuous basis functions (in order to satisfy the well-known LBB stability criterion, cf. Schunk, et al. 2002). This option enables interpolating and smoothing the hydrodynamic pressure to nodal values that most post-processors can deal with (e.g. BLOT, Mustafa). This variable is called PRESSURE in the output EXODUS II file.

The permissible values for this postprocessing option are:


Calculate the pressure contours.


Do not calculate the pressure contours.
