NeqSim Java/Python API patterns for fluids, flashes, process equipment and units. USE WHEN: selecting EOS/mixing-rule selection and property retrieval, including viscosity, thermal conductivity, binary/effective diffusion, gas-oil-water interfacial tension and black-oil PVT table conversion. Follow linked references for exact model selection, initialization and tested examples.
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
# NeqSim API Patterns Copy-paste reference for common NeqSim operations. All Java code must be Java 8 compatible. Use progressive disclosure: search headings and read only the task-relevant section. For property-model selection, diffusion or gas-oil-water interfacial tension, read [references/physical-properties.md](references/physical-properties.md) and its tested guides. For black-oil tables, conversion and reservoir export, use `docs/blackoil/README.md` and the `pvt-simulation` agent. For APIs absent from this recipe list, follow [source/runtime discovery](../../../docs/development/AGENT_CAPABILITY_DISCOVERY.md). ## MCP server vs. Python/Java API — which to use **Default policy: MCP first.** For any single calculation, always check whether a NeqSim MCP tool (`mcp_neqsim_*`) already covers it before writing Python or Java. Only drop to code when MCP genuinely cannot do the job. Concretely: 1. **Curated tool exists** (`runFlash`, `runProcess`, `runPVT`, `getPhaseEnvelope`, `sizeEquipment`, `calculateStandard`, `runFlowAssurance`, `runBatch`, ...) → use it directly. Confirm field names with `getSchema`/`validateInput` first. …

How to install
mdr add equinor/neqsim/neqsim-api-patterns@sha256:8e73b933880ce0b3The line at the top of this page pins the label git:20261026.7e867ed, 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.
