Date: 2026-09-05 Purpose: One-layer CORC cable with a translated periodic boundary condition.

What it shows

This deck models one layer of three REBCO tapes wound around a round core, as thin shells. A translated periodic condition shifts the top plane along the axis, so each tape connects to itself. A 160 A, 50 Hz sine drives the cable for 20 ms with Picard and STRUMPACK. Compare it with corc_garber_effect, which uses a twisted periodic condition.

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.
