5.4. Performing a Mode-Superposition Transient Dynamic Analysis
The mode-superposition method scales the mode shapes obtained from a modal analysis and sums
them to calculate the dynamic response. For more detailed information, see Mode Superposition
Method in the Mechanical APDL Theory Reference.
This method is available in the ANSYS Multiphysics, ANSYS Mechanical, ANSYS Structural, and ANSYS
Professional products. The procedure to use the method consists of five main steps:
- Build the model.
- Obtain the modal solution.
