BUCOPT -- Specifies buckling analysis options. The Subspace iteration eigensolver has been added to the list of available eigensolvers. Also, the default behavior has been changed to find the lowest magnitude negative and positive modes centered around 0.0. Previously, the lowest magnitude positive modes were found by default.

CINT -- Defines parameters associated with fracture parameter calculations. The new VCCT option (for CINT,TYPE) calculates energy-release rate parameters using the VCCT method

/CONFIG -- Assigns values to ANSYS configuration parameters. The default value for the maximum number of results sets allowed on the results file (the NRES parameter) has increased from 1000 to 10000. Similarly, the default for the NUMRESLT keyword in the config140.ans file has changed to 10000.

DJ -- Specifies boundary conditions on the components of relative motion of a joint element. This command now allows the predefined %_FIX% table name for input of the boundary condition value, meaning that the program will prescribe (lock) the degree of freedom to the current displacement value.

*DMAT -- Creates a dense matrix (APDL Math). The new Method = RESIZE option allows you to resize an existing matrix. The new Method = LINK option allows you to link to an existing matrix, thus providing a means to manipulate a submatrix of the original matrix.

DSUM -- Specifies the double sum mode combination method. The new ForceType option allows you to specify the forces being combined.

EQSLV -- Specifies the type of equation solver. The AMG solver has been undocumented; it is recommended that you use the PCG solver instead.

*EXPORT -- Exports a matrix to a file (APDL Math). You can now export a matrix in the DMIG file format.

FS -- Stores fatigue stress components at a node. Now allows the input of time.

*GET -- Retrieves a value and stores it as a scalar parameter or part of an array parameter. Capabilities have been extended after a Campbell analysis (Entity = CAMP). You can now retrieve the stability (real part of the eigenvalue) for each mode and rotational velocity step as well as the instability key. Also, modal assurance criterion values can now be retrieved as parameters using Entity = RSTMAC.

NRLSUM -- Specifies the Naval Research Laboratory (NRL) sum mode combination method. The new ForceType option allows you to specify the forces being combined.

PCGOPT -- Controls PCG solver options. The new LM_Key option allows use of the PCG solver when MPC184 Lagrange multiplier method elements are present in the model.

PERTURB -- Sets linear perturbation analysis options. Support for linear perturbation eigenvalue buckling and full harmonic analyses has been added. In addition, the new MatKey = TANGENT is an alternate material option which specifies that material properties in the perturbation analysis be accounted for by using the tangent (material Jacobian) on the material constitutive curve at the restart point of the base analysis.

PLCAMP -- Plots Campbell diagram data for applications involving rotating structure dynamics. Support is now available for the plotting of all frequencies (positive and negative) obtained with the DAMP eigensolver. This new option (keyNegFreq) may be needed when damping is important and overdamped frequencies are present.

PRCAMP -- Prints Campbell diagram data for applications involving rotating structure dynamics. Support is now available for the printing of all frequencies (positive and negative) obtained with the DAMP eigensolver. This new option (keyNegFreq) may be needed when damping is important and overdamped frequencies are present.

/RENAME -- Renames a file. In distributed parallel mode (Distributed ANSYS), you can now specify that the rename operation be performed on all distributed processes.

RESCONTROL -- Controls file writing for multiframe restarts. The new MAXFILES = -1 option allows restart files (Jobname.Xnnn) to continue to be written after the maximum limit of 999 files is reached; the .Xnnn file numbering is reset to 1, and existing Jobname.Xnnn files are overwritten. (This is the new default behavior.)

RESP -- Generates a response spectrum. You can now specify an acceleration input time-history (inputType = 1).

RESWRITE -- Appends results data from the database to a results file. This command can now be used (in conjunction with the RESCOMBINE command) to write a global results file for a distributed parallel (Distributed ANSYS) solution.

ROSE -- Specifies the Rosenblueth mode combination method. The new ForceType option allows you to specify the forces being combined.

SECDATA -- Describes the geometry of a section. This command now supports the definition of circular contact sections associated with 2-D contact/target elements.

SECFUNCTION -- Specifies shell section thickness as a tabular function. The command now accepts (via KCN) either a local coordinate system reference number or an array interpretation pattern for the tabular function evaluation. When KCN = NOD2, the program interprets TABLE as a 2-D array parameter (where columns contain node numbers and rows contain the corresponding thicknesses) that expresses the function to be mapped.

SECTYPE -- Associates section type information with a section ID number. The command now has support for circular contact sections associated with 2-D contact/target elements.

*STATUS -- Lists the current parameters and abbreviations. The new Par = MATH option allows you to list APDL Math parameters.
