Public Members

double dt

Time step for vvm [s].

double dx

Grid size in x-direction [m].

double dz

Grid size in z-direction [m]. It should be the same as dx.

int XRANGE

Domain size of the model in x-direction [m].

int ZRANGE

Domain size of the model in z-direction [m].

double TIMEEND

End time of the simulation [s].

int TIMEROUTPUTSIZE

The size of the timer output.

std::string outputpath

The path for the output file. It should be a directory, such as “/data/vvm/”.

int OUTPUTSTEP

The output interval for the output file.

double Kx

The eddy diffusion coefficient in x-direction [m^2/s], this is activated when DIFFUSION flag is turned on. If the flag is not turned on, the coeffcient will be calculated through the turbulent closure.

double Kz

The eddy diffusion coefficient in z-direction [m^2/s], this is activated when DIFFUSION flag is turned on. If the flag is not turned on, the coeffcient will be calculated through the turbulent closure.

double TIMETS

The time filter coefficient [s] for Leapfrog. This is activated when TIMEFILTER flag is turned on. Only need to turn on when Leapfrog is used.

double tolerance

The tolerance for the Poisson Solver.

double GRAVITY

The gravity acceleration [m/s^2]. It’s 9.80665 m/s^2 for default.

double Cp

The specific heat capacity at constant pressure [J/kg/K]. It’s 1003.5 J/kg/K for default.

double Cv

The specific heat capacity at constant volume [J/kg/K]. It’s 716.5 J/kg/K for default.

double Rd

The gas constant for dry air [J/kg/K]. It’s 287 J/kg/K for default.

double Lv

The latent heat of vaporization [J/kg]. It’s 2.5E6 J/kg for default.

double P0

The reference pressure [Pa]. It’s 1E5 Pa for default.

double PSURF

The surface pressure [Pa]. It’s 96500 Pa for default.

double addforcingtime

The time for adding the perturbation. The perturbation is used to break the symmetry of the model.

int CASE

The case number for the model. It’s used to specify the initial condition and the forcing. If CASE is 0, the initial condition is equal to mean state. If CASE is 1, the initial condition is equal to mean state plus a warm bubble.

double mositure_nudge_time

The time for nudging the moisture. It’s used for nudging the moisture to the mean state. It’s used for nudging the moisture to the mean state.
