hpc-calculix

hpc-calculix is a skill for Codex from SciMate-AI/HPC-Skills. It costs 62 tokens per session (550 once invoked), scanned A, original, MIT.

A guide for working with CalculiX, a finite-element program for simulating physical systems. It focuses on .inp input files, which describe the model, materials, loads, constraints, and analysis steps.

In plain words
What is it for?
Use it to create, review, debug, and automate CalculiX simulations, including static, frequency, thermal, coupled, contact, time-controlled, and cluster-based analyses.
Why use it?
It helps prevent mismatches between the mesh, element types, materials, boundary conditions, loads, and requested analysis. It also helps diagnose solver and post-processing failures.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hpc-calculix scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (assets/templates/calculix-ccx-slurm.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HPC CalculiX

Treat CalculiX as an input-deck-driven FEM workflow centered on .inp keywords.

Start

  1. Read references/input-deck-manual.md before creating or editing a .inp file.
  2. Read references/keyword-and-step-matrix.md when mapping materials, sections, loads, and analysis steps.
  3. Read references/mesh-boundary-and-output.md when working with nodes, elements, sets, boundary conditions, and result output.
  4. Read references/cluster-execution-playbook.md when staging a CalculiX deck for scheduler-backed cluster execution.
  5. Read references/error-recovery.md when parsing, solving, or post-processing fails.

Additional References

Load these on demand:

  • references/time-control-and-amplitudes.md for step time, amplitude logic, and incremental loading behavior
  • references/result-files-and-postprocessing.md for .dat, .frd, and eigenmode artifacts
  • references/thermal-and-coupled-procedures.md for heat transfer and coupled analysis patterns
  • references/step-load-output-matrix.md for procedure-to-load-to-output compatibility tables
  • references/element-section-material-matrix.md for element, section, and material assignment lookup tables
  • references/error-pattern-dictionary.md for structured parse, singularity, and procedure-mismatch failure signatures
  • references/cluster-execution-playbook.md for launch style, result-artifact planning, and cluster-side deck execution

Reusable Templates

Use assets/templates/ when a concrete .inp scaffold is needed, especially:

  • static_minimal.inp
  • frequency_minimal.inp
  • thermal_minimal.inp
  • beam_static.inp
  • calculix-ccx-slurm.sh

Guardrails

  • Do not invent Abaqus-style keywords that CalculiX does not support.
  • Do not mix node or element set names inconsistently across sections and steps.
  • Do not define loads and boundary conditions without checking the active step type.
  • Do not skip material and section coherence when the deck fails later in the solve.

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hpc-calculix is a skill published in the GitHub repository SciMate-AI/HPC-Skills (86 stars, last pushed 5mo ago), licensed MIT. It adds 62 tokens to every session and 550 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
