Space Simulation: Driving Innovation Across Launch, Satellite & Deep-Space Vehicles
Getting hardware to orbit (and keeping it there) means mastering extreme temperatures, vacuum, radiation, and dynamic loads that no terrestrial product ever sees. Ansys’ digital engineering platform unifies propulsion CFD, structural and thermal FEA, guidance & control analysis, antenna/RF modelling, and real-time mission simulation so your teams can design, verify, and operate confidently from concept to constellation.
Propulsion & Ascent Dynamics
Ground Systems, Launch & Propulsion
- Cryogenic tank and feed-line thermal stability
- Nozzle acoustics, plume/vehicle interaction, and stage-separation dynamics
- Re-entry aerothermodynamics and TPS life prediction
- GNC software V&V through model-based development
Deployables, Electronics & Radiation
Satellite & On-Orbit Platforms
- Lightweight composite & deployable-structure sizing under launch vibro-acoustics
- Orbital thermal balance, radiator sizing, and cryocooler integration
- Radiation-hardened electronics, single-event effects, and latch-up analysis
- High-gain antenna, phased-array, and inter-satellite link (ISL) optimization
Tracking, Collision Avoidance & Mission Ops
Space Situational Awareness & Constellation Management
- Rapid orbit determination, conjunction assessment, and collision probability using STK + ODTK
- Communications link margin and RF interference studies across thousands of assets
- Constellation-scale power, thermal, and attitude modelling for life-of-mission planning

End-to-End Mission Modeling & Assurance
System-Level Integration & Mission Readiness
Digital mission engineering brings physics-based subsystem models into the same timeline and orbital context used by flight-dynamics teams. Space systems engineering teams can evaluate thermal gradients during eclipse, verify antenna pointing during momentum dumps, or test de-orbit burn profiles against conjunction constraints, months before hardware leaves the cleanroom.
End-to-end “chip-to-mission” traceability
Early discovery of cross-discipline bottlenecks (e.g., RF shadowing by solar arrays)
Automated Monte-Carlo risk sweeps for launch window & abort-mode planning
