Hi,

Is it possible to ask Abaqus to solve for a subset of modes in a frequency band, instead of the whole frequency band or specified number of modes? I'd like to figure out if there is a way I can run an analysis to solve for just the modes with responses in the X and Y DOF, and not solve for the rest to improve run times. Many of the modes in the band have mode shape values of 0 for all X and Y DOF. I know I can request just X and Y coordinates after solving, but I would like to improve efficiency in running the model and ask it not to solve for the rest of the modes.

Thank!

Debby
