Date: 2026-09-05 Purpose: 2D tape stack resolved layer by layer.

What it shows

An 11-tape two-dimensional stack with each tape layer resolved as a thin shell. Each tape includes copper, silver, YBCO, buffer, and Hastelloy, using built-in materials. The superconductor uses the built-in power law. The stack carries a 160 A ramp. Compare with tapestack2d_racetrack, which uses a table-driven superconductor and a copper bulk.

Files

file	role
tapestack.geo	geometry (mm); mesh it with gmsh
input.conf	deck

Run

gmsh -2 tapestack.geo -o tapestack.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.
