请看下面说明，希望对楼主有益！ Specifying Analysis Settings for Each Step The following items can be changed on a per step basis: Step Controls, Nonlinear Controls, and Output Controls. Nonlinear Controls and Output Controls are discussed in their own sections. Details of Step Controls: Current Step Number shows the step ID for which the settings in Step Controls, Nonlinear Controls, and Output Controls are applicable. The currently selected step is also highlighted in the bar at the bottom of the Timeline window. You can select multiple steps by selecting rows in the data grid or the bars at the bottom of the Timeline window. In this case the Current Step Number will be set to multi-step. In this case any settings modified will affect all selected steps. Step End Time shows the end time of the current step number. When multiple steps are selected this will indicate multi-step. Auto Time Stepping is discussed in detail in the Automatic Time Stepping section. Automatic time stepping is available for static and transient analyses, and is especially useful for nonlinear solutions. Settings for controlling automatic time stepping are included in a drop down menu under Auto Time Stepping in the Details View. The following options are available: •Program Controlled (default): Simulation automatically switches time stepping on and off as needed. A check is performed on nonconvergent patterns. The physics of the simulation is also taken into account. •On: You control time stepping by completing the following fields that only appear if you choose this option. No checks are performed on nonconvergent patterns and the physics of the simulation is not taken into account. ◦Initial Substeps: Specifies the size of the first substep. The default is 1. ◦Minimum Substeps: Specifies the minimum number of substeps to be taken (that is, the maximum time step size). The default is 1. ◦Maximum Substeps: Specifies the maximum number of substeps to be taken (that is, the minimum time step size). The default is 10. •Off: No time stepping is enabled. You are prompted to enter the Number Of Substeps. The default is 1. Define By allows you to set the limits on load increment in one of two ways. You can specify the Initial, Minimum and Maximum number of substeps for a step or equivalently specify the Initial, Minimum and Maximum time step size. Carry Over Time Step is an option available when you have multiple steps. This is useful when you do not want any abrupt changes in the load increments between steps. When this is set the Initial time step size of a step will be equal to the last time step size of the previous step. Time Integration is valid only for a flexible dynamic or transient thermal analysis. This field indicates whether a step should include transient effects (for example, structural inertia, thermal capacitance) or whether it is a static (steady-state) step. This field can be used to set up the Initial Conditions for a transient analysis. •On: Default for transient analyses. •Off: Do not include structural inertia or thermal capacitance in solving this step. |
