Why use NSMB

Built for Hypersonics

NSMB is a high-fidelity solver built for hypersonic workflows, combining high-temperature chemistry, radiation, moving bodies, and coupled multiphysics in one validated foundation.

NSMB in practice

Confidence across the full envelope

At Mach 1.2, with engines firing and grid fins deployed, reusable launcher faces shock–plume interaction, rapidly shifting loads, and sensitive control authority. NSMB gives engineering teams the high-fidelity physics to resolve these coupled effects before they become design risk.

NSMB for re-entry

Predict re-entry heating with confidence

NSMB helps teams predict high-fidelity surface heat flux when re-entry leaves little margin for uncertainty. Accurate thermal loads make it possible to size thermal protection, assess materials, and steer critical design decisions with confidence.
