In the Analysis/Print Commands dialog box I see two iteration options for DIRECT ANALYSIS as shown next. Can you please explain what these are ?
The first one controls the number of iterations used for Taub computation. Usually 1 to 10 iterations is good enough with default being 1. If the number is set to 0, default of 1 is used. The second one controls the number of iterations used for computing Pdelta effects ( large+small). The second set of iterations may be considered as a subset of the first one or in other words, for every iteration of Taub, you will have a bunch of Pdelta iterations ( default 15 )
