PIHM-utils 1.0.3

Python scripts to read MM-PIHM input and output files

PIHM-utils

Library for reading MM-PIHM input and output files.

Installation

To install:

pip install PIHM-utils

Usage

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.
