SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Early-stage process and facilities concepts need a quick sanity check that proposed design capacities and conditions carry sensible margins over operating values before committing to detailed mechanical design. This Skill assembles a screening design basis, computes indicative margins, and flags values below transparent public thresholds. ## Core Features & Use Cases - Margin Screening: Computes flow and pressure margins as design/operating ratios and temperature margin as a design-minus-operating difference, comparing each against configurable thresholds (defaults 1.10 and 10 C). - Standards-Basis Echo: Normalizes and echoes the declared design standards list (e.g., ASME VIII Div.1, NORSOK P-001) and flags a missing standards basis. - Flagged Verdicts: Returns ok/low flags per margin plus an overall ok/watch design warning with human-readable explanations. - Use Case: An engineer screening a new separator concept enters operating flow of 100, design flow of 120, operating pressure of 60 bara, and design pressure of 70 bara, and immediately sees which margins fall below recommended thresholds before escalating to validated NeqSim mechanical design. ## Quick Start Ask the agent to run a design-basis screening with your operating and design flow, pressure, and temperature values plus the applicable standards list, then review the returned margins and flags.

Frequently Asked Questions about neqsim-design-basis-screening

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check design margins for flow, pressure, and temperature in Python?▼

Instantiate DesignBasisModel and call evaluate with operating and design flow, pressure in bara, and temperature in Celsius. It returns flow and pressure ratios, a temperature difference, and ok/low flags against default thresholds of 1.10 and 10 C.

What is a design basis screening in process engineering?▼

A design basis screening compares proposed design capacities and conditions against operating values to confirm sensible margins before detailed engineering. This Skill computes indicative margins and echoes the standards basis, but performs no code rating or wall-thickness calculation.

Can this replace ASME or NORSOK mechanical design calculations?▼

No. It is an educational placeholder that performs no code-rating, wall-thickness, or mechanical-design check. Any quantitative or design use must be escalated to validated NeqSim mechanical-design classes and the applicable ASME, API, DNV, or NORSOK standards.

Does the design basis screening require NeqSim to be installed?▼

No. The package has zero required dependencies and runs standalone. It only reports whether the optional neqsim package is importable via the neqsim_available field in the result.

Why does the screening return a watch verdict?▼

A watch verdict appears when any margin falls below its threshold or when no standards basis is supplied. The flags field lists each issue, such as a flow margin below the recommended 1.10 ratio.
