To run a simulation, Mantaflow needs a python setup file.

Mantaflow config file consists of following parts:
:1. Data declaration
:2. Flow setup
:3. Flow solving steps

=== Data declaration ===
It is used to define the solver data, such as solver resolution, types of grids that will be used in simulation and their properties.
Things that can be done here:
*Create solver given resolution(at least)
*Create grids(velocity,pressure, flags,density):
**MAC grid
**Real grid
**Flag grid
**Vector grid
* Create Mesh types:
** Box, given pMin and pMax
** Cylinder, given radius and center
*Import existing meshes
*Other variables that may be used in scrips(maybe properties added by users)

=== Flow Setup ===
Here, domain initialization takes place.

=== Flow Solving Steps ===
The main part where simulation takes place
Things that can be done here:
*Flow advection
*Adding external forces
*Pressure solve step
*Density Inflow declaration
*Wall Boundaries setup
*Buoyancy setup

=== Wavelets setup ===
If wavelet turbulence must be included in the simulation, two solvers(low- and high res) must be created. During the flow solving steps, low-res data must be transferred to high-res grid, and the turbulence should be added afterwards.

=== Values ===
Table of all values that can be used for Blender smoke setup, and their corresponding mantaflow configs
