neqsim-dynamic-process-preparation

neqsim-dynamic-process-preparation is a skill for Claude Code, Codex from equinor/neqsim-community-skills. It costs 62 tokens per session (1,505 once invoked), scanned A, original, Apache-2.0.

A preparation workflow for making a NeqSim process model ready for dynamic simulation, meaning a simulation that follows changes over time. It checks equipment volumes, liquid holdup, mechanical design, initialization, and transient-run settings.

In plain words
What is it for?
Use it to prepare ProcessSystem or ProcessModel flowsheets, estimate equipment design, set liquid levels and holdups, initialize the model, and configure transient runs.
Why use it?
Steady-state models often lack the volumes and starting conditions needed for a meaningful time-based run. This workflow helps identify and prepare those missing pieces before simulation.

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

neqsim-dynamic-process-preparation 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 4 executable files (examples/basic_dynamic_preparation.py, src/dynamic_process_preparation/__init__.py, src/dynamic_process_preparation/model.py, …), 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.

Dynamic Process Preparation

Use this skill when an agent must prepare a NeqSim ProcessSystem or multi-area ProcessModel for dynamic calculations. It focuses on model-readiness checks, mechanical-design handoff, equipment holdup and volume initialization, and the transient run sequence.

When to Use

  • When a user asks to turn a steady-state NeqSim process into a dynamic-ready process.
  • When a ProcessSystem or ProcessModel needs equipment volumes, holdups, or initial liquid levels before transient simulation.
  • When an agent needs a documented workflow for run(), storeInitialState(), setTimeStep(...), and runTransient().
  • When mechanical design should be estimated with NeqSim classes before dynamic calculations.

Inputs

  • process_name: public process or model name used in reports.
  • process_kind: ProcessSystem or ProcessModel.
  • equipment: dynamic candidate equipment records with name, equipment_type, optional length_m, diameter_m, liquid_level_fraction, and requires_mechanical_design.
  • time_step_seconds: proposed transient time step.
  • total_time_seconds: optional total transient duration.
  • initialization_basis: steady-state case, public design point, or synthetic example basis.

Outputs

  • dynamic_ready: boolean indicator for whether the supplied preparation metadata passes basic checks.
  • equipment_actions: per-equipment actions such as enable dynamic mode, estimate mechanical design, set vessel geometry, and set initial level.
  • estimated_volumes_m3: geometric cylindrical volume estimates for public readiness checks when dimensions are supplied.
  • neqsim_sequence: NeqSim API sequence for initialization and transient execution.
  • warnings: missing information or setup gaps that should be fixed before transient calculations.

Engineering Method

The Python class DynamicProcessPreparationModel is a public planning and validation helper. It does not run NeqSim itself. It checks that a dynamic-ready NeqSim workflow has the minimum metadata needed to initialize dynamic equipment and points the user to the NeqSim APIs that should do the real work.

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.

neqsim-dynamic-process-preparation is a skill published in the GitHub repository equinor/neqsim-community-skills (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 62 tokens to every session and 1,505 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 2026-08-31.
