Reviewers fund technology they believe works. These are the twenty simulation applications that show up again and again across defense solicitations — each paired with the Ansys tools that model it and the programs that fund it. Click any tile to see how Ansys helps you build and validate it. If your work is on this list, simulation isn't optional. It's your proof.
At Mach 5+, flight tests are rare and wind tunnels limited — high-fidelity CFD plus thermal/structural simulation is the enabling technology for airframes, TPS, and RF blackout.
Short-duration, severe loading — penetration, fragmentation, and progressive structural failure of armor and vehicles under explicit dynamics.
Full-wave 3D EM design of antennas and phased arrays, co-site interference, and mission-context RF performance for radar and comms.
Chip-, board-, and enclosure-level cooling for SWaP-constrained defense electronics where heat is the limiting factor.
Scramjet combustion, rocket engines, and turbomachinery — reacting-flow CFD coupled with structural and thermal analysis.
Structural launch loads, on-orbit thermal cycling, and full mission design — coverage, orbits, and link budgets.
PCB, package, and chip-level signal/power integrity and electro-thermal reliability for advanced microelectronics.
Electric machines, motor drives, and power electronics — electromagnetic design coupled with thermal and flow.
Aerodynamics, lightweight structures, and crash/impact behavior for autonomous air vehicles and Blue UAS platforms.
Beam control, optical systems, and thermal management for high-energy lasers and photonics payloads.
Predict and shape radar signature — RCS of airframes and structures, plus radar-absorbing materials — before you ever reach a test range.
Model dense RF environments — jamming, spectrum management, and co-site interference between every emitter and receiver on a platform.
Cell-to-pack thermal, fast-charge behavior, and thermal-runaway propagation for the batteries powering drones, sensors, and directed-energy systems.
Predict distortion, residual stress, and microstructure in metal 3D-printed parts — the qualification bottleneck for defense AM.
Virtually qualify hardware against random vibration, shock, and fatigue so it survives the field — and the MIL-STD-810 test lab.
Hull hydrodynamics, cavitation, seakeeping, and underwater signature for surface and subsurface maritime platforms.
Blade aerodynamics, rotordynamics, and aeromechanics for turbines, compressors, and turbopumps.
Laminate design, progressive failure, and damage tolerance for the lightweight composite structures defense platforms depend on.
Design integrated photonics and quantum hardware — waveguides, modulators, and photonic circuits — at the device and system level.
Model whole constellations and missions — coverage, revisit, link budgets, and space-domain awareness across many assets at once.
Then you need Ansys — and the engineers who know how to drive it. Let's talk about evaluation licenses and live support, before or after your funding comes through.
