Overview
A Python library for interpreting Finite Element Method Magnetic (FEMM) files and exposing FEMM solution data
through a Python attribute-based interface. FEMMInterpreter exposes the A-field as A(x,y), independent of
planar or axisymmetric coordinate systems.
Proposed Integration
FEMMInterpreter is intended to provide a bridge between FEMM's numerical solutions and Python-based computational models.
FEMM Setup & Solve → FEMM (.ans) → FEMMInterpreter → Reduced Order Models / Analytical Models
Figure 1: Magnetic vector potential of a dipole extracted from FEMM (.ans)
[!NOTE]
This example of a dipole being plotted can be found in /examples with
.ansand.pyfiles.
Quick Start
from FEMMInterpreter import Parser
# Imports the parser and parses the .ans file
PATH = "examples/magnetostatic.ans"
data = Parser.open(PATH)
# Result as a float with implicit unit of wb/length_unit
a_potential = data.point_potential(0, 0)
[!IMPORTANT]
This tool will focus on the magnetic domain for now, but can be expanded in the future to cover all FEMM solutions.
Installation
[!WARNING]
This library is still under development and hasn't been fully documented nor fully test-covered.
The abstraction boundaries may change with future releases.
To install,
pip install FEMMInterpreter
Documentation
Documentation for the attribute class output can be found here.
Internal documentation can be found within this repo's issues.
