FetoFlow

Overview

FetoFlow is a small library for constructing simplified placental vascular networks from simple mesh files, computing vascular resistances (including an analytical capillary equivalent model) and solving for nodal pressures and element flows. The code is organised around a networkx directed graph representation where each edge stores attributes such as length, radius, resistance and edge_id.

The documentation is structured into module-level pages describing:

• parsing utilities (file_parsing_utils)

• geometry construction (geometry_utils)

• resistance computations (resistance_utils)

• matrix assembly (matrix_builder)

• solver routines (solve_utils)

• high-level pipeline (pressure_flow_utils)

• developer tools (tools)

Quick start

A minimal example of running a simulation:

from FetoFlow.file_parsing_utils import read_nodes, read_elements
from FetoFlow.pressure_flow_utils import pressures_and_flows

bcs = {'inlet_pressure': 12000, 'outlet_pressure': 0}
pressures_and_flows('placenta.ipnode', 'placenta.ipelem', bcs, inlet_radius=0.002, strahler_ratio_arteries=0.79)

See the module pages for detailed descriptions of functions and keyword arguments.
