Eigensolver and linear-solver options (solver) keyword reference¶

Input-file keywords read by Eigensolver and linear-solver options (solver), grouped by the block that contains them, with the type and default value taken from the code. A blank Default means the code supplies no fixed value when the keyword is absent, or the entry is a block or switch. Presence required means the run stops without it. What each keyword does is explained in the module guides and the command syntax pages.
