charRho
Characteristical Density [Si]
true
decimal
1
Density factor rho in kg/m^d. As average latticeRho is always around 1, specify the average physical density here.
At some point latticeRho can be multplied by this factor to get the local physical density.

true
decimal
0
This additive pressure constant in Pa is added to the relative pressure result of the computation
to get the absolute value.
