Description
|
|
This boundary condition provides static pressure condition for p_rgh,
|
|
calculated as:
|
|
|
|
\f[
|
|
p_rgh = p - \rho g (h - hRef)
|
|
\f]
|
|
|
|
where
|
|
\vartable
|
|
p_rgh | Pseudo hydrostatic pressure [Pa]
|
|
p | Static pressure [Pa]
|
|
h | Height in the opposite direction to gravity
|
|
hRef | Reference height in the opposite direction to gravity
|
|
\rho | density
|
|
g | acceleration due to gravity [m/s^2]
|
|
\endtable

\verbatim
|
|
myPatch
|
|
{
|
|
type prghPressure;
|

rho rho;
|
|
p uniform 0;
|
|
value uniform 0; // optional initial value
