SWBPIPE helps readers develop a design: route the line, arrange supports, try alternatives and understand the behavior. It does not judge code compliance or vouch for its results. When the design needs validation, it goes to the program your industry accepts. The code check is made there under your engineer’s judgment.

One seat of the accepted program can support validation of work developed by several designers. Current .mbf output is a bounded interchange smoke subset, not a complete or qualified transfer. Target version, record-family coverage and direct stable-ID carrying remain open. Other export packages also have their own bounds.

The desktop .mbf panel renders a bounded smoke subset. It emits node coordinates, pipe connectivity and references, minimal support records, and load-case IDs/types. The text carries target IDs and load kinds; the sidecar maps source IDs to target IDs. It omits component records and does not carry the full physical model. Each package includes a sidecar ID map, loss report and diagnostics. Target version and record-family coverage remain unresolved; the package does not establish CAEPIPE compatibility.

1.Other exports.

Other surfaces prepare a straight-run PCF subset, native packages, CSV or JSON result exports, centerline geometry and local-detail handoffs. These packages have different input, loss and eligibility conditions. A package’s presence does not establish target compatibility or professional validation.

All desktop output surfaces refuse successor pressure-1 results and load/reference-state results, including load-reference-1 and load-reference-source-1. These results remain readable with the Rust product reader’s verdict and standing. Readability does not grant output eligibility. Fresh desktop report packages are unavailable. Historical precision-1 results remain readable but are not Current, rule-, report- or export-eligible.

Retained-precision F2a D1 remains registered development/test work without a public production caller. Saved or copied result bytes do not supply the live native capture required by prepared successor policies. Prepared result JSON and stress-neutral policies admit a successor only with eligible standing and a live native capture. This policy preparation does not activate the successor. Other successor output surfaces remain refused.

2.How the export will be checked.

A complete interchange check must compare three representations: the defined problem, a model built by hand in the receiving program, and the exported model. Each feature must be identified as exact, approximate, omitted or untested. A file that opens does not establish faithful transfer. Current smoke-subset checks screen package structure and disclosed losses; they do not establish complete target execution or equivalence (Part VI).

Equivalent models can give similar movements and loads in two programs, but their results need not be identical. Differences can arise from each program’s assumptions and implementation. Understanding those choices helps reconcile the results.

Compare the models before their results. Compare geometry, sizes, materials, support types and directions, and load cases, row by row.

1.A reconciliation order.

• Weight only, with every support rigid: support loads should agree closely.
• Thermal only, without friction and with nonlinear supports held in one state: movements and anchor loads should agree within the effect of shear deformation and bend modeling.
• Then add pressure, springs, friction and nonlinear supports one at a time. Explain each change in the difference before adding the next.

Where the programs still disagree, the model in the validating program is the design basis under your engineer’s judgment.
