"""
Takes information from initializer and runs necessary functions to perform
a one-dimensional simulation. Simulation results will be saved if booleans
are set to True.
Parameters
----------
mech : str
A .cti mechanism file containing all reaction and species information.
arrtype : str
Defines the scale that conditions are in. Either linear or logarithmic
pres : list
A list of pressure conditions to test over [initial, final, number of points].
temp : list
A list of temperature conditions to test over [initial, final, number of points].
fue : str or list
As a string the variable represents a single species of fuel being used.
As a list the variable represents multicomponent fuel species
followed by the percentage to the total fuel [Component1, % of total, ...]
oxi : str or list
As a string the variable represents a single species of oxidizer being used.
As a list the variable represents multicomponent oxidizer species
followed by the percentage to the total oxidizer [Component1, % of total, ...]
dilu : str or list
As a string the variable represents a single species of diluent being used.
As a list the variable represents multicomponent diluent species
followed by the percentage to the total diluent [Component1, % of total, ...]
mix_params : list
A list of the two mixture parameters and mixtrue type used in creating
a mixture.
safi : boolean
If true simulation conditions and ranking results will be saved.
par : bool
If true, run simulations in paralle
Mingrid: int
Number of points to be solved in the simulation
Mul_soret : boolean
Multicomponent diffuction and Soret effect are calculated if true
Loglevel : int
A number from 1 to 10. The larger the number the more information that
is printed during the simulation to the user.
Returns
-------
None.
