Chapter 2: Loading 2.6.1.6. Other General Options You can also specify the following general options: • The reference temperature for thermal strain calculations, which defaults to zero degrees. Specify this temperature as follows: Command(s): TREF GUI: Main Menu> Preprocessor> Loads> Load Step Opts> Other> Reference Temp Main Menu> Preprocessor> Loads> Define Loads> Settings> Reference Temp Main Menu> Solution> Load Step Opts> Other> Reference Temp Main Menu> Solution> Define Loads> Settings> Reference Temp • Whether a new factorized matrix is required for each solution (that is, each equilibrium iteration). You can do this only in a static (steady-state) or transient analysis, using one of these methods: Command(s): KUSE GUI: Main Menu> Preprocessor> Loads> Load Step Opts> Other> Reuse LN22 Matrix Main Menu> Solution> Load Step Opts> Other> Reuse LN22 Matrix By default, the program decides whether a new matrix is required, based on such things as changes in DOF constraints, temperature-dependent material properties, and the Newton-Raphson option. If KUSE is set to 1, the program reuses the previous factorized matrix. This setting cannot be used during a multiframe restart. The command KUSE,-1 forces the factorized matrix to be reformulated at every equilibrium iteration. Analyses rarely require this; you will use it mainly for debugging purposes. To generate and keep the Jobname.LN22 file, issue the command EQSLV,SPARSE,,,,KEEP command. • A mode number (the number of harmonic waves around the circumference) and whether the harmonic component is symmetric or antisymmetric about the global X axis. When you use axisymmetric harmonic elements (axisymmetric elements with nonaxisymmetric loading), the loads are specified as a series of harmonic components (a Fourier series). To specify the mode number, use one of the following: Command(s): MODE GUI: Main Menu> Preprocessor> Loads> Load Step Opts> Other> For Harmonic Ele Main Menu> Solution> Load Step Opts> Other> For Harmonic Ele See the Element Reference for a description of harmonic elements. • The type of scalar magnetic potential formulation to be used in a 3-D magnetic field analysis, specified via one of the following: Command(s): MAGOPT GUI: Main Menu> Preprocessor> Loads> Load Step Opts> Magnetics> potential formulation method Main Menu> Solution> Load Step Opts> Magnetics> potential formulation method • The type of solution to be expanded in the expansion pass of a reduced analysis, specified via one of the following: 58 Command(s): NUMEXP, EXPSOL GUI: Main Menu> Preprocessor> Loads> Load Step Opts> ExpansionPass> Single Expand> Range of Solu's Main Menu> Solution> Load Step Opts> ExpansionPass> Single Expand> Range of Solu's Main Menu> Preprocessor> Loads> Load Step Opts> ExpansionPass> Single Expand> By Load Step Release 13.0 - © SAS IP, Inc.
