Summary (AI generated)

Earlier, I described how the Flow heats up the material under thermal and aerodynamic loads, potentially causing deformation. To analyze this situation, we must couple the hypersonic Flow with material response, specifically Structural Response. This collaboration with Professor Kurt Ma from Colorado involves using the Morris element code to model the Structural Response. The sequence of images demonstrates how the coupling is achieved, starting with the original geometry of a Hypersonic Inlet where flow is from left to right. Initially, the CFD code Le Mans is applied.
