Before beginning with selectASET, several FEM preprocessing steps are required in Nastran to generate the TAM and model data that will be imported into the selectASET GUI. These instructions assume that the user has already selected target modes for the modal test as well as the candidate set DOF. For a thorough discussion of the process of selecting the candidate set DOF and TAM generation, see the “Model Preparation” section of the Genetic Algorithm for Accelerometer Placement user’s guide here.
