Evaluates the current total pressure and related physical quantities in the simulation zone.

PressureTotal determine the gas and line radiation pressures for current conditions, this sets the variable pressure.PresTotlCurr

This function computes the total pressure at the current zone, including contributions from gas, ram, turbulent, magnetic, and radiation (line and continuum) pressures. It also updates related quantities such as radiative acceleration, enthalpy density, and tracks the dominant contributors to the radiation pressure. The function manages evaluation frequency based on simulation state and flags, and ensures physical consistency of the results.

The function is central to the equation of state calculations in the simulation and is called once per zone.

Todo

2 this is the total binding energy of the molecules, and is negative, the energy need to get back to free atoms never set and only appears in print statements

Todo

0 add this press term due to cosmic rays - hextra.cr_energydensity

Todo

0 code has variable magnetic energydensity and pressure, which are equal, as they must be - del one or the other
