Transient modal dynamic analysis

A modal dynamic analysis:

  • is used to analyze transient linear dynamic problems using modal superposition;

  • can be performed only after a frequency extraction procedure since it bases the structure's response on the modes of the system;

  • can use the high-performance SIM software architecture (see Using the SIM architecture for modal superposition dynamic analyses);

  • can include nondiagonal damping effects (i.e., from material or element damping) only when using the SIM architecture; and

  • is a linear perturbation procedure.
