Integrating MBSE with Digital Mission Engineering Aerospace and Defense
Digital Mission Engineering (DME) Accelerates Capability Delivery
Continuing mission-focused performance
assessment throughout the lifecycle using
a common mission model reduces rework
and improves stakeholder communication
Accomplishing mission-focused
performance assessment early in the
lifecycle reduces delivery time and cost

Integrate Ansys MBSE Tools with Other Data, Tools, and Workflows
• Multiple integration approaches exist to support any digital engineering environment
ModelCenter’s black box approach enables The Minerva SPDM tool provides a single
integration of disparate tools into common ASoT for mission engineering data,
workflows (e.g., costing, meshes, PLM/PDM) optimizes simulation workflows, and
connects to the broader digital engineering
ecosystem
TETK automates import of data from external sources,
allowing your STK-based MBSE/DME analysis to be
enhanced with data generated by your broader Test &
