Product: Abaqus/Standard
Benefits: Enhanced functionality and improved performance are now available in complex eigenvalue extraction analysis.
Description: You can now perform complex eigenvalue extraction analysis using the high-performance SIM architecture. SIM-based complex eigenvalue extraction analysis offers the following benefits:
structural damping, including damping defined with viscoelastic materials, is taken into account;
modal damping can be specified;
matrices representing the stiffness, mass, and damping can be defined;
the AMS eigensolver can be used to generate the projection subspace for the complex eigenvalue extraction; and
the analysis time is reduced significantly.
