A guide for building, checking, debugging, and automating SU2 computational-fluid-dynamics workflows. SU2 is software that simulates how fluids such as air and water move around objects.

Use it when creating or editing SU2 configuration files, selecting compressible or incompressible solvers, mapping mesh markers, running cases on clusters, monitoring convergence, or processing results.

It helps translate mesh boundaries, solver settings, convergence checks, restarts, and cluster execution into a consistent configuration-driven workflow.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.00444
Opus 5	$0.00029	$0.00222
Sonnet 5	$0.00012	$0.00089
Haiku 4.5	$0.00006	$0.00044

Security

Grade A, and why

hpc-su2 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (assets/templates/su2-cfd-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.

What it actually says

HPC SU2

Treat SU2 as a configuration-driven CFD stack centered on the .cfg file.

Start

Read references/config-and-workflow.md before creating or editing a SU2 case.
Read references/marker-and-boundary-matrix.md when mapping mesh markers to physical boundaries.
Read references/convergence-and-execution.md when choosing solver settings, execution commands, and convergence controls.
Read references/cluster-execution-playbook.md when staging a SU2 case for scheduler-backed cluster execution.
Read references/error-recovery.md when the config, mesh import, or run fails.

Additional References

Load these on demand:

references/solver-and-physics-matrix.md for solver-family and physics option selection
references/output-restart-and-history.md for OUTPUT_FILES, history fields, and restart policy
references/time-domain-and-multizone.md for transient, windowed convergence, and multizone workflows
references/cluster-execution-playbook.md for launch style, restart control, and cluster-side convergence monitoring

Reusable Templates

Use assets/templates/ when a concrete config skeleton is needed, especially:

incompressible_steady.cfg
compressible_external_aero.cfg
unsteady_windowed.cfg
su2-cfd-slurm.sh

Guardrails

Do not invent config keywords outside documented SU2 options.
Do not mismatch mesh marker names and config marker sections.
Do not assume compressible and incompressible setups share the same variable conventions.
Do not ignore convergence history and residual trends during solver tuning.

Outputs

Report:

solver family
mesh and marker assumptions
key config sections touched
convergence and output files expected

Files

What ships with it

13 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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-su2 is a skill published in the GitHub repository SciMate-AI/HPC-Skills (85 stars, last pushed 5mo ago), licensed MIT. It adds 58 tokens to every session and 444 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.
