Simscale

SimScale via sim

Use this skill when driving SimScale through sim-plugin-simscale.

Safety First

• Never print or commit SIMSCALE_API_KEY.
• Treat pasted keys as compromised and rotate after validation.
• Check estimates before starting mesh or simulation compute.
• Record the SimScale project ID, simulation ID, run ID, compute resource, and Workbench URL in the final evidence.

Basic Commands

sim check simscale
sim connect --solver simscale --ui-mode no_gui
sim inspect session.summary
sim inspect simscale.spaces
sim exec '{"command": "list_projects"}'
sim disconnect

Smoke Recipe

sim-plugin-simscale v0 supports one guarded recipe:

kind: pipe_junction_incompressible_smoke
name: Agent smoke run
max_compute_cpu_hours: 0.5

Run it with:

sim run --solver simscale recipe.yaml

Expected artifacts:

• .sim/runs/<run-id>/metadata.json
• .sim/runs/<run-id>/events.json
• .sim/runs/<run-id>/probe_points.csv

Validation Guidance

For routine code changes, use mocked tests and uv build; do not start cloud compute. For release validation, run one live smoke from a fresh install, then inspect the downloaded probe CSV and metadata.

Stop and report if:

• sim check simscale cannot see spaces or projects.
• estimate exceeds the requested CPU-hour limit.
• SimScale reports authorization, billing, or credit errors.
• geometry mappings for the bundled fixture are not unique.
