Simcenter 3D Space Systems Thermal (SST) is a specialized solution for modeling and simulating the thermal behavior of spacecraft and satellite systems. Built on Simcenter 3D, SST combines advanced radiation and conduction modeling with CAD integration, enabling fast and accurate thermal predictions. Engineers can simulate orbit scenarios, evaluate thermal control strategies, and optimize system performance early in the design process. With SST, space system developers gain a comprehensive thermal analysis environment to reduce design risk, meet mission requirements, and accelerate innovation.
