SMX122 - Dynamic Analysis using SimXpert

Horizontal spacer

SMX122 is an introductory course in vibration simulation using the Structures Workspace in SimXpert. Students will prepare models utilizing imported geometry and geometry created in SimXpert. Students will learn to mesh and manually create elements, to create properties, time and frequency dependent loading, boundary conditions, and simulation conditions. Students will also learn to review results from these models using plots and charts.
