Library for reading MM-PIHM input and output files.
To install:
pip install PIHM-utils
The read_mesh
function reads mesh information from MM-PIHM .mesh
input files:
from pihm import read_mesh
num_elem, num_nodes, tri, x, y, zmin, zmax = read_mesh(pihm_dir, simulation)
where num_elem
is the number of triangular elements,
num_nodes
is the number of nodes, tri
is an array of triangles consisted of nodes,
x
, y
, zmin
, and zmax
are arrays of the x and y coordinates, and bottom and surface elevations of nodes, respectively.
pihm_dir
is the path to the MM-PIHM directory, which should contain input
and output
directories,
and simulation
is the name of the simulation.
The read_river
function reads river information from MM-PIHM .river
input files:
from pihm import read_river
num_rivers, from_nodes, to_nodes, outlets = read_river(pihm_dir, simulation)
where num_rivers
is the number of river segments,
from_nodes
and to_nodes
are arrays of from and to nodes of river segments,
and outlets
is an array of river outlets.
The read_output
function reads MM-PIHM simulation output files:
from pihm import read_output
sim_time, sim_val, desc, unit = read_output(pihm_dir, simulation, outputdir, var)
where sim_time
is an array of simulation time steps,
sim_val
is an array of output values containing simulation results from all model grids at all model steps,
and desc
and unit
are strings containing description and unit of the specific output variable.
outputdir
is the name of the output directory,
and var
is name of output variable.
For a complete list of available output variables, please refer to the MM-PIHM User's Guide.
Please check out the interactive Python notebook for a visualization example.
