momwire

A pure-Python method-of-moments antenna simulator with optional C++ accelerators (pybind11).

Extracted from antenna_designer.

Install

python3 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install -e .

macOS: the C++ accelerator uses Homebrew's OpenMP runtime, so brew install libomp is required — both to compile from source and to run the prebuilt Apple-Silicon wheel. The wheel deliberately does not bundle libomp (it links Homebrew's by absolute path) so that it shares a single OpenMP runtime with pynec-accel; two private copies in one process abort with OMP: Error #15 (or deadlock). Without libomp installed, the accelerator can't load and momwire warns and falls back to the slower pure-Python path. On Linux the system libgomp covers this, so no extra step is needed.

Test

pip install -e ".[test]"   # core + test deps (pytest, matplotlib, scikit-rf)
pytest tests/

The cross-validation against NEC2 (tests/test_pynec_backend.py) additionally needs PyNEC — a test-only dependency installed separately from a wheel (see below). Those tests skip cleanly when it isn't present; everything else runs without it.

Optional: PyNEC backend (test-only)

momwire can be cross-validated against NEC2 via PyNEC (the tests/test_pynec_backend.py suite); NEC2 also delivers ~5–10× faster single-frequency solves. PyNEC is a test-flow-only dependency — momwire's own solver never imports it.

Install the PyNEC wheel

Install PyNEC from the python-necpp fork's release. The distribution is named pynec-accel (the import name stays PyNEC); the wheels are self-contained — OpenBLAS is vendored (via scipy-openblas32), so no system BLAS, SWIG, or build toolchain is needed — and cover Linux, Windows, and macOS (arm64) on CPython 3.10–3.14:

pip install pynec-accel --no-index \
    --find-links https://github.com/stevenmburns/python-necpp/releases/expanded_assets/v1.7.6

--no-index ensures pip takes the fork's wheel rather than upstream PyNEC on PyPI (which is broken on current Python and lacks the OpenBLAS/OpenMP work). On macOS the wheel shares Homebrew's libomp (brew install libomp) rather than vendoring its own, so it can coexist with momwire's accelerator in one process. After install, from PyNEC import nec_context works and the cross-validation tests run; without it they're skipped (momwire itself needs no PyNEC).

Runtime thread pinning

The wheel links OpenBLAS and parallelises the NEC2 matrix fill with OpenMP. Pick thread counts up front:

export OMP_NUM_THREADS=$(nproc --all)   # PyNEC matrix fill
export OPENBLAS_NUM_THREADS=1           # muzzle numpy/scipy's idle pool

Pinning OPENBLAS_NUM_THREADS=1 stops numpy/scipy from spinning up their own OpenBLAS thread pool that contends with PyNEC's threads on the same cores. On a 100-director Yagi (2142 segs) this is worth ~8% wall time at NP=4.
