Date: 2026-09-05 Purpose: 2D dipole coil: the simplest deck.

What it shows

A two-dimensional dipole made of two bulk coil blocks in air, driven by a 1 A sine current of 2 s period with opposite polarity in the two blocks. Nothing else is switched on: no superconductor, no thin shells, no iron, no coupling. Start here to see a complete deck and the output it produces before moving to the HTS cases.

Files

file	role
dipole.geo	geometry; mesh it with gmsh
input.conf	deck

Run

gmsh -2 dipole.geo -o dipole.msh

../../build/bin/belfem # or mpirun -np 4 ../../build/bin/belfem

Shared launcher

../scripts/Allrun generates the mesh, chooses ranks and threads, and can submit to Slurm; ../scripts/Allclean removes run output. To use them from this directory, copy the two wrapper scripts Allrun and Allclean from examples/helix/ here and run ./Allrun (./Allrun --dry-run prints the plan first). If you copy this deck out of the tree, copy examples/scripts/ along with it and point the wrappers at its new location. The launcher does not build plugins; do that step by hand as described above. Per-deck settings go in a run.conf next to input.conf; see ../scripts/README.md.
