What is the recommended procedure for solving multiple spectra with expansion
in a separate pass?
|
The documented procedure utilizing multiple load steps for the mutliple spectra could be used. When you do multiple load steps, the mode coefficients for each spectrum (load step) are written to file.mode. The subsequent expansion then looks at all the MCs for all the spectra to determine which modes to expand. ! Solution Pass 1 Modal Extraction (no expansion) ! Solution Pass 2 ( 3 load steps ) Spectrum 1 (no combination) Spectrum 2 (no combination) Spectrum 3 (no combination) ! Solution Pass 3 Modal Expansion of significant modes ! Solution Pass 4 Spectrum 1/2/3 combination |
