• The LIST DYNAMIC PARTICIPATION FACTORS Command was given the ability to output the mass participation factors in a tabulated form sorted by mode, by one of the global directions, or by each one of the global directions. By default, the output will only show active modes. However, the user can specify if the output should include all modes. The command can also output only totals in each global direction.

• The efficiency of the LIST MAXIMUM JOINT DISPLACEMENTS and LIST MAXIMUM REACTIONS commands has been dramatically improved when the analysis results are stored on external save files using the GTSES/GT64M sparse equation solvers. For jobs consisting of large models with tens and even hundreds of loading conditions, the time to execute these commands has decreased from an hour or more for the largest jobs to a few minutes at most.

• The MATERIAL command now respects the EXISTING MEMBERS ONLY and the EXISTING ELEMENTS ONLY options for a member list. Previously, the ONLY specification was ignored and the material properties (E, DENSITY, etc.) were assigned to all members and elements in the EXISTING list.

• The COUTPUT command will now assume COUTPUT standard if an invalid file name is specified. An invalid file name can be due to illegal characters in the name, or restrictive permissions on the folder where the file is attempting to open.

• Support for nonlinear geometric behavior has been implemented for the SBHQ, SBHQ6, SBHT, and SBHT6 plate finite elements. The nonlinear geometric behavior capability is designated for these elements by the NONLINEAR EFFECTS command in a manner identical to way it is done for frame and truss members. This capability is only available for the GTSES solver option.

Nonlinear (cont)Nonlinear (cont)• Nonlinear analysis has been extended to support the

GTSES sparse equation solver. The GTSES solver is executed for nonlinear static analysis when the NONLINEAR ANALYSIS GTSES command is given or when the ACTIVE SOLVER GTSES command is given prior to any NONLINEAR ANALYSIS commands. When nonlinear analysis uses the GTSES solver, it also stores the analysis results into files, rather than in memory. The GTSES solver in conjunction with the storage of results in files provide nonlinear static analysis with the ability to solve significantly larger problems with much greater speed and efficiency.

An example of the performance improvement using the GTSES solver is shown on the next slide
