description	Run Cubit .jou files in Cubit 2025.12 and export mesh via the current Cubit .ccm export commands
allowed-tools	Bash(python ), Bash(coreform_cubit), Bash(ssh ), Bash(cp ), Bash(sed ), Bash(cat *), Read, Glob, Write

Cubit .jou Runner & Tester

CURRENT POLICY (2026-07-06): target Coreform Cubit 2025.12 and the cubit_mesh_export.ccm APREPRO commands (export netgen/gmsh/vtk/... and export jmag_nastran). The old radia_export ... verb and Cubit 2025.3 paths are historical. Prefer C:\temp for temporary journals and outputs.

Run Cubit journal (.jou) files and test all export formats.

Arguments

Argument	Action
`<path/to/file.jou>`	Run a single .jou file with full export test suite
`test` or `tests`	Run all tests in `tests/cubit/export_mixed_test/`
`test 100`	Run tests on 100号機 via SSH

Full Export Test Suite (per .jou)

For EVERY .jou file tested, run ALL of these export formats:

CUBIT="C:\Program Files\Coreform Cubit 2025.12\bin\coreform_cubit.exe"

# Generate test .jou from the user's .jou by appending export commands
# The user's .jou should contain geometry + mesh + blocks only (no export)
# Append these export lines with output to a temp directory:

export gmsh "{DIR}/test.msh" order 1 overwrite
export gmsh "{DIR}/test_o2.msh" order 2 overwrite
export jmag_nastran "{DIR}/test.bdf" order 1 overwrite
export jmag_nastran "{DIR}/test_o2.bdf" order 2 overwrite
export vtk "{DIR}/test.vtk" order 1 overwrite
export vtk "{DIR}/test_o2.vtk" order 2 overwrite
export netgen "{DIR}/test_o1.vol" order 1 overwrite
export netgen "{DIR}/test_o2.vol" order 2 overwrite
export netgen "{DIR}/test_o3.vol" order 3 overwrite
export netgen "{DIR}/test_o4.vol" order 4 overwrite
export netgen "{DIR}/test_o5.vol" order 5 overwrite

Verification checklist (per file)

File exists and size > minimum threshold
HEX20/TET10 connectivity: for order 2 .msh, verify element node count matches GMSH type (type 17 = 20 nodes, type 11 = 10 nodes)
p-convergence monotonic: .vol file sizes should increase with order (order N+1 > order N)
No "Interrupt Detected" in Cubit output

Running on 100号機

# Copy .jou to 100号機 via SMB
cp test.jou "//192.168.11.100/c$/temp/test.jou"

# Run via SSH
ssh 100 '& "C:\Program Files\Coreform Cubit 2025.12\bin\coreform_cubit.exe" -batch -nographics -nojournal C:\temp\test.jou 2>&1 | Select-String "Exported|succeed|FAIL|Interrupt"'

# Verify: all lines show "Exported" or "succeeded", no "Interrupt"

Existing test suite

# Run all registered tests (local)
python tests/cubit/export_mixed_test/run_test.py

# Tests included:
# 1. Mixed hex+tet+pyramid: order 1+2, gmsh+nastran+vol
# 2. Hex cylinder: order 2, gmsh+nastran (HEX20 = 20 nodes check)
# 3. Sphere p-convergence: order 1-5, vol

Export commands (APREPRO)

Command	Format	Orders	Notes
`export gmsh "f.msh" order N version 2`	GMSH v2.2	1-4
`export gmsh "f.msh" order N version 4`	GMSH v4.1	1-4
`export radia_nastran "f.bdf" order N`	Nastran BDF	1-2	NOT `export nastran` (built-in conflict)
`export vtk "f.vtk" order N`	VTK Legacy	1-2
`export meg "f.meg"`	MEG/ELF	1 only
`export netgen "f.vol" order N`	Netgen Vol	1-5	p-convergence test
`coil "script.py"`	CoilBuilder STEP	--	subprocess Python 3.12

Troubleshooting

Interrupt Detected on AddPoint: ABI mismatch. Rebuild ccm with compact_netgen (not full Netgen DLL).
HEX20 has 8 nodes: edge_ho_nodes_ not registered for volume element edges. Fixed 2026-04-05.
Non-zero exit code (0xC0000005): Cubit cleanup crash. Check output files, not exit code.
cp932 UnicodeDecodeError: Non-ASCII in .jou filename or .py panel. Use ASCII only.
topLevelWidgets error: Batch mode (-nographics). Harmless, panels skip registration.

release-qud

ksugahar/Radia

Four-machine Radia release gate. Use when the user asks for release-qud, release_quad, release_qud, post-release deploy, GitHub Release publication, or the Definition Of Done for Radia releases. Coordinates PyPI and Simulink release candidates across LAB, 100号機, mdx, and hibino via tools/release_qud.py.

2026-07-3110

publish-panel

ksugahar/Radia

Publish Radia's Simulink application library after verifying its five application blocks and tracked MATLAB-only samples. Use simulink-app-health before deploy/release-qud; Cubit's toolbar remains a separate deployment surface.

2026-07-2310

simulink-app-health

ksugahar/Radia

Verify Radia's production Simulink application blocks for EM, PCB, Motor, Stream Function, and IH. Use after changing buildLibrary, applicationSFunction, runApplication, application.py, a DesignSpec/calc script, the application interface manifest, or the tracked Simulink library; also use when a block does not run or leaves incomplete artifacts.

2026-07-2310

api-inventory

ksugahar/Radia

Take inventory of the radia package's proprietary Python and pybind API surface, classify API families under the Reduce Proprietary API Surface policy, and produce a committed audit plus phased reduction plan. Use after public API changes, before deprecation work, or for periodic read-only surface audits.

2026-07-2210

deploy

ksugahar/Radia

Historical deploy notes. Current Radia deploy/release uses release-qud plus cubit-plugin-install; do not follow old .ccl/Cubit-2025.3 recipes except for archaeology.

2026-07-2210

gmsh-verify

ksugahar/Radia

Verify GMSH .geo + .msh files generated by Radia panels BEFORE opening in the GUI. Catches invalid options (Mesh.Volumes), duplicate element IDs, missing Merge targets, node count mismatches. Run AFTER any calc_*.py edit that touches GMSH export, BEFORE clicking Open GMSH.
