meenpy is a library of utilities for mechanical engineering problem solving.

meenpy.numerics enables the succinct articulation equations, efficient assembly of systems, and provides a transparent solving interface.

Installation

Check out the package manager uv and add meenpy to your project or workspace.

uv add meenpy

Alternatively, install meenpy directly with pip.

pip install meenpy

Usage

import numpy as np, sympy as sym, pandas as pd
from meenpy.numerics import ScalarEquation, MatrixEquation, TabularEquation, System
from meenpy.numerics.utils import *

## Variable Definitions
T, x, p, v = sym.symbols("T, x, p, v")
T_amb, h, Qd = sym.symbols("T_amb, h, Qd")
column_map = {T: "Temperature", x: "Quality", p: "Pressure", v: "Specific Volume"}

## Equation Definitions
water = TabularEquation(pd.read_csv("test/assets/water.csv"), ["Temperature", "Quality"], residual_type="all_column_differential")
convection = ScalarEquation(Qd, h * (T - T_amb))

## System Composition and Solution
water_system = System([water, convection], column_map)
water_system_solution = water_system.solve({T_amb: 25, h: 1, Qd: 100}, {T: 100})
