neqsim-column-internals-and-rate-based SKILL.md skillA
neqsim-column-internals-and-rate-based from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add equinor/neqsim/neqsim-column-internals-and-rate-based@git:20261004.fc23e28Pins git:20261004.fc23e28 in mdr.lock. Pin the fingerprint instead.

Guides agents in choosing equilibrium-stage versus rate-based packed columns, selecting solvers, sizing trays/packing, and checking hydraulic limits. USE WHEN: a user asks about tray or packing selection, column diameter, flooding, weeping, pressure drop, HETP, mass-transfer rates, or solver choice. Anchors: DistillationColumn, ShortcutDistillationColumn, PackedColumn, RateBasedPackedColumn, ColumnInternalsDesigner, TrayHydraulicsCalculator, and PackingHydraulicsCalculator.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Column Internals and Rate-Based Contactors ## When to use this Use this skill to select and inspect NeqSim's distillation/contacting model class, evaluate tray or packing hydraulics, or decide whether the task needs equilibrium-stage VLE or explicit rate-based mass transfer. This complements `neqsim-distillation-design`: that skill remains the detailed reference for ordinary `DistillationColumn` setup, specification combinations, solver troubleshooting, convergence gates, feed placement and Fenske/Underwood/Gilliland checks. Do not duplicate its full workflow; use this skill for model-class boundaries and internals/hydraulic APIs. ## Class map | Class | Package | What it does | Verified API surface | |---|---|---|---| …

How to install
mdr add equinor/neqsim/neqsim-column-internals-and-rate-based@sha256:3c091108984cbfdeThe line at the top of this page pins the label git:20261004.fc23e28, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
