SMX124 - Thermal Analysis (SOL400) using SimXpert

Horizontal spacer

SMX124 is an introductory course in heat transfer simulation using the Structural Workspace in SimXpert.  Students will prepare thermal models utilizing imported MSC Nastran finite element models, geometry created in SimXpert, and hex mesh created by sweeping quad elements.  Students will learn how to create a temperature constraint, thermal heat flux LBC, internal heat generation LBC, free convection LBC, radiation to space LBC, radiation enclosure, variable direction solar LBC, and transient thermal result. Students will also learn to review thermal results for these thermal models using State Plot and Chart.
