Reviewers and investors fund technology they believe works. These are the simulation applications that prove it — each paired with the Ansys tools that model it. If your work is on this list, simulation isn't optional; it's your evidence.
How funded hardware teams turn FEA, CFD, and electromagnetics results into the evidence funders score — before machining anything.
Every payload gets shaken hard on the way up. Predict the random-vibration and vibro-acoustic response of your structure, find the resonances that will crack a bracket or a solder joint, and size the design to the launch vehicle's spec before you ever book a shaker table.
Launch providers require a coupled-loads analysis and a first-mode above a threshold. Run modal and frequency-response analysis to prove your spacecraft's stiffness, avoid coupling with the launch vehicle, and clear the launch-readiness gate.
In vacuum there's no convection — only radiation and conduction. Model hot and cold orbital cases, sunlit-to-eclipse swings, and thermal-vacuum test conditions so your electronics and optics stay inside their survival limits without a heater budget you can't afford.
Coming home is the hard part. Simulate hypersonic reentry aerothermodynamics, shock heating, and heatshield ablation to size the thermal protection system and keep the internal cargo — a returned sample, a pharmaceutical, an instrument — from cooking.
Model the combustion, injector mixing, and nozzle expansion of chemical thrusters, and the conjugate heat transfer into the chamber wall. Predict thrust, specific impulse, and wall temperatures so hot-fire tests confirm the model instead of discovering surprises.
Electric propulsion lives or dies on the magnetic circuit and plasma behavior. Simulate the magnetic field of a Hall thruster and the electromagnetics of the power train, then couple to plasma and thermal models to push efficiency and lifetime.
Design and place patch arrays, horns, and reflector antennas; predict gain, pattern, and coupling on a crowded spacecraft body. Simulate the RF payload so your link closes and neighboring antennas don't blind each other.
Model orbits, ground-station passes, revisit and coverage, and the end-to-end link budget for your constellation. Prove your mission concept and coverage claims with a real dynamics model instead of a spreadsheet estimate.
A sub-millimeter particle at orbital velocity carries a lot of energy. Run explicit hypervelocity-impact simulations on shielding and pressure vessels to size Whipple shields and prove MMOD survivability for your mission duration.
Deployment is a single-shot event you can't fully rehearse on the ground. Simulate the dynamics of unfolding solar arrays, booms, and antennas — latch loads, snap dynamics, and stowed-launch strength — so the one deployment that matters works.
High-speed avionics boards need clean signals and stable power rails, and EMI margin in a tight enclosure. Simulate signal integrity, power delivery, and board-level EMI so your flight computer isn't the thing that fails the EMC test.
Thermal cycling and launch vibration fatigue solder joints and components over a mission. Run physics-of-failure reliability analysis to predict which joints crack first and design the board to survive the full mission life.
Composite-overwrapped pressure vessels and propellant tanks carry huge stored energy. Model burst margin, cyclic fatigue, and composite layup so your tank meets factor-of-safety requirements without carrying dead mass to orbit.
Star trackers, imagers, and optical inter-satellite links need optical performance that holds under thermal distortion. Simulate the optical train and the structural-thermal-optical (STOP) coupling so your instrument stays in focus on orbit.
In-space manufacturing depends on fluid, thermal, and solidification physics that behave differently without gravity. Model the melt, crystal growth, or bioprint process to design the hardware and predict product quality before you buy ISS rack time.
