femmreader

Femmreader is a parser to read files from the Finite Element Software femm.

Following files are supported. Model files:

• *.fem (Magnetics problem)
• *.fee (Electrostatics problem)
• *.fec (Current flow problem)
• *.feh (Heat flow problem)

Result files:

• *.ans (Result file of magnetics problem)
• *.anc (Result file of current flow problem)
• *.res (Result file of electrostatics problem)
• *.anh (Result file of heat flow problem)

Installation

femmreader is a pure python package with no dependencies. Install via

pip install femmreader

Usage

Let's have a look on a very basic example.

Read the file with

imoprt femmreader
data = femmreader.read("EI-core.FEM")

print(data.keys())
>>> dict_keys(['Format', 'Frequency', 'Precision', 'MinAngle', 'DoSmartMesh', 'Depth', 'LengthUnits', 'ProblemType', 'Coordinates', 'ACSolver', 'PrevType', 'PrevSoln', 'Comment', 'BdryProps', 'BlockProps', 'CircuitProps', 'NumPoints', 'NumSegments', 'NumArcSegments', 'NumHoles', 'NumBlockLabels'])

print(data['Depth'])
>>> 20

The same for result files:

data = femmreader.read("EI-core.ans")

print(data.keys())
>>> dict_keys(['Format', 'Frequency', 'Precision', 'MinAngle', 'DoSmartMesh', 'Depth', 'LengthUnits', 'ProblemType', 'Coordinates', 'ACSolver', 'PrevType', 'PrevSoln', 'Comment', 'BdryProps', 'BlockProps', 'CircuitProps', 'NumPoints', 'NumSegments', 'NumArcSegments', 'NumHoles', 'NumBlockLabels', 'Solution'])

print(data['Solution'].keys())
>>> dict_keys(['xpos', 'ypos', 'sol_real', 'sol_imag', 'solution', 'elements', 'block_labels'])
