How to use the diffusion.DiffusionComponent function in diffusion
To help you get started, we’ve selected a few diffusion examples, based on popular ways it is used in public projects.

def initialize(self, input_stream=None):
# If no input file/stream specified, use default (or command line?)
# (or default values?)
if input_stream is None:
input_stream = str(raw_input('Enter name of input file: '))
# Open input file
inputs = ModelParameterDictionary(input_stream)
# Create grid
self.grid = create_and_initialize_grid(inputs)
# Create a diffusion component
self.diffusion_component = diffusion.DiffusionComponent(self.grid)
self.diffusion_component.initialize(input_stream)
# Read parameters
self.run_duration = inputs.get('RUN_DURATION', ptype=float)
self.opt_netcdf_output = inputs.get('OPT_FILE_OUTPUT', ptype='bool')
self.opt_display_output = inputs.get('OPT_DISPLAY_OUTPUT', ptype='bool')
self.setup_output_timing(inputs)
