Limitations • Not supported if Prestress environment is nonlinear. • Domain Decomposition option is not supported during pre-stressed harmonic analysis. • Only supported for either single field structural or pure acoustics system. • Cyclic symmetry is not supported. • Perfectly matched layers (PML) and Irregular perfectly matched layers (IPML) are not supported. • Incident wave source is not supported. • Contacts with keyopt(2) = 3 is not supported. i.e., contacts with normal Lagrange formulation is not supported. • Only Fixed Joint with solver element type set to Contact/Direct or Bushing Joint with Bushing formulation are supported. • Frequency dependent matrices and loading can be included in the analysis, but they may impact the accuracy of the Krylov method.
