176 ©2023 ANSYS, Inc. Mode-Superposition Analysis Exposed in 2023R2 (was beta in 2023R1) in both MAPDL and Mechanical: • Residual vector method is supported by QRDAMP mode extraction method. • For direct combination of element results (Elcalc=YES on SPOPT) in SPRS and DDAM analyses, a new key (SpecCum on SPOPT) enables the cumulation of response spectra solutions written on the results file. For SPRS analysis, it facilitates accurate postprocessing of an analysis with multiple response spectra and missing mass effect activated (MMASS,ON). This allowed the exposure of direct results combination in Mechanical for Response Spectrum leading to huge gain in time. 0 50 100 150 200 250 300 350 400 450 500 50 100 150 200 Total time (s) Number of Modes Solution time vs Number of modes 23R2 23R1 Solution time on model #2 Example mode #1
