Represents incremental linear static problem. The problem is solved as series of linear solutions and is intended to be used for solving linear creep problems or incremental perfect plasticity. Nonzero value of optional parameter renumber turns on the equation renumbering to optimize the profile of characteristic matrix (uses Sloan algorithm). By default, profile optimization is not performed. It will not work in parallel mode.

Supports the changes of static scheme (applying, removing and changing boundary conditions) during the analysis.

Response is computed in times defined by prescribedTimes array. These times should include times, when generally the boundary conditions are changing, and in other times of interest. (For linear creep analysis, the values should be uniformly distributed on log-time scale, if no change in loading or boundary conditions). The time at the end of interested is specified using endOfTimeOfInterest parameter.
