LqdSprdGaussianGasDisp Command

DispersionSpreadModels.LqdSprdGaussianGasDisp(tag, MatTags, OutFlowModelTags, MinDisThickness=0.01, Surface_Roughnesslist=[], Surface_RoughnessThickness=[], Vaporization_Delta_t=10, TotalDuration=1800, GasConstant=8.31446261815324, GasDispersionXSegments=10, GasDisperstionErrorPercent=1)

This command is for modeling the spread of the liquids and then calculate its gas dispersion in the environment. So, it is appropriate for liquids that their gas dispersions are important to be considered.

Argument	Type	Description
Tag	int	Unique integer value that will be used for referring to the defined elements or objects.
MatTags	list of int	List of defined materials that user wants to consider this module for them as their behavior.
OutFlowModelTags	list of int	List of outflow models that this model can happen after happening them.
MinDisThickness	list of float	Minimum thickness of the liquid until it has not reached to the dike wall (if dike has been defined before). If user do not define any value for this parameter, it will be considered equal to 0.01 m.
Surface_Roughnesslist	list of float	List of existing surfaces roughness’s.
Surface_RoughnessThickness	list of float	list of Thickness values corresponding to each Roughnesslist value.
Vaporization_Delta_t	float	steps time distance for vaporization calculations.
TotalDuration	float	total time of vaporization.
GasDispersionXSegments	int	number of segments that are considered to calculate the dispersion and also dispersed mass of gas.
GasDisperstionErrorPercent	float	Error percentage for numerical calculations.

Example:

Create some imaginary materials:
