Linear static analysis. Parameter nsteps indicates the number of loading cases. Series of loading cases is maintained as sequence of time-steps. For each load case an auxiliary time-step is generated with time equal to load case number. Load vectors for each load case are formed as load vectors at this auxiliary time.

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.

The sparselinsolverparams parameter describes the sparse linear solver attributes and is explained in section 6.17. Can be used in parallel mode. The input record must be the same for all processors. At present, parallel version requires PETSc module.
