Weight BOM source control
Part and assembly detail rolls upward into controlled mass properties reports.
MassMasterTM
Govern aircraft mass properties data across every source that changes the design.
MassMasterTM is a distributed change-control system for aircraft weight, CG, inertia, source, effectivity, and configuration knowledge, keeping weight BOMs, reports, distributed outputs, and simulation models traceable as aircraft configurations evolve.

Abaqus roadmap
Controlled source data
More than CAD-derived weight.
Mass properties source data comes from CAD, Nastran / Abaqus FEM models, PLM / ERP enterprise records, measured weights, supplier data, hardware records, legacy databases, payload definitions, morphed derivative estimates, and engineer-authored calcsheets.
MassMasterTM gives those sources a governed home outside CAD while maintaining traceability to source, credibility, and configuration.
Engineer-friendly calcsheets
Excel workbooks can retain calculation detail, images, notes, and supporting artifacts.
Dictionary extension
Customer-specific fields can travel with the governed data model.
How MassMaster works
Source data, governance, and outputs stay connected.
CAD, Nastran / Abaqus FEM, PLM / ERP enterprise systems, measured weights, suppliers, hardware, legacy databases, calcsheets, payloads
Distributed repository, custom dictionaries, source records, credibility, MGA, effectivity, revision history, branch, review, baseline, and merge
Weight BOM roll-ups, function-code summaries, credibility reports, distributed mass properties, FEM and simulation support
Pilot acceptance criteria
- Representative legacy data migration and dictionary mapping.
- Weight BOM roll-up and report output alignment.
- Configuration and effectivity validation.
- Distributed mass-property workflow value for loads, dynamics, or simulation.
- Repository governance and contributor workflow fit.
Repository-based control
Git-style configuration control without reducing MassMaster to a database story.
Relational databases may store records; MassMasterTM governs configuration change. Its repository-based architecture reduces infrastructure overhead and supports portable, high-performance engineering workflows.
With Git-style change control, teams gain complete history, branching, comparison, review, baselining, merging, restoration, contributor tracking, and distributed collaboration.
Extensible migration path
Preserve the data model that already matters.
Custom dictionaries allow customers to extend the MassMasterTM data model without forcing every legacy field into a rigid vendor schema. This reduces migration risk and lets programs validate new workflows while retaining familiar data structures.

Reproducible baselinesRestore prior reports, releases, and simulation input states.
FEM-aware mass properties
Capture mass distribution where early trades are actually made.
MassMasterTM Nastran support is a major advantage because FEM models often contain composite layup schedules and distributed mass detail before CAD can fully represent those trades.
MassMasterTM can also help conform mass properties back into FEM workflows so structural dynamics, loads, flutter, and simulation models reflect better controlled mass data. Abaqus support should remain roadmap language until released.
Effectivity and configuration
Track options, events, dates, kits, payloads, and fleet states.
MassMasterTM supports configuration-specific effectivity logic for option studies, kits, payloads, temporary installations, regulatory test events, as-built states, delivery states, and fleet tracking.
