Detailed Description

Stokes equation model descriptor.

Members of these Stokes equation model descriptor are publicly accessible, to allow for concise syntax, as it is expected to be used in many places.

Field Documentation

arak

Arakawa multiplicator for the Rhie and Chow filter (1 by default)

epsdp

parameter of diagonal pressure strengthening

icalhy

compute the hydrostatic pressure in order to compute the Dirichlet conditions on the pressure at outlets

• 1: true
• 0: false (default)

iccvfg

calculation with a fixed velocity field

• 1: true (default)
• 0: false

idilat

algorithm to take into account the density variation in time

• 1: dilatable steady algorithm (default)
• 2: dilatable unsteady algorithm
• 3: low-Mach algorithm

igprij

improve static pressure algorithm

iifren

indicates the presence of a Bernoulli boundary face (automatically computed)

• 0: no face
• 1: at least one face

iphydr

improve static pressure algorithm Take into account the balance or imbalance between the pressure gradient and source terms (as gravity and head losses)

• 1: impose the equilibrium of the hydrostaic part of the pressure with any external force, even head losses

take

rnormp

normed residual for the pressure step
