Icepak瞬态分析设置

Icepak瞬态分析设置


To solve a transient problem, you will follow the procedure outlined below:
1. Enable the Transient option in the Transient setup tab of the Basic parameters panel (Figure 26.1.1). To open the Basic parameters panel, double-click on the Basic parameters item under the Problem setup node in the Model manager window.

2. Enter the starting and ending times for the simulation in the Start and End text fields.
3. To edit the default transient parameters (if required), click on Edit parameters. This will open the Transient parameters panel shown in Figure 26.1.2.

(a)Specify a value for the Time step increment. The default value is 0.001 s. The specified Time step increment will be used for all time steps if Uniform is selected. It will also be used if Piecewise linear is selected and  (see below).

(b) Specify the Solution save interval. This value tells ANSYS Icepak how often during the solution procedure the results should be saved. Every tenth time step is saved by default.
Only steps that have been saved can be used during postprocessing. Large amounts of data can be generated from a transient simulation, so you should decide how much data should be saved for postprocessing. If you are only interested in the solution at the end of the transient simulation, then very little intermediate data need be saved. If you are interested in animating and studying the transient effects in detail, then almost every time step should be saved.

(c) Specify whether ANSYS Icepak should use a uniform or non-uniform time step.
Uniform specifies a uniform time step. The value of the Time step increment will be used for all time steps.
Variable specifies a non-uniform time step. There are three options:
Linear  ) specifies a linear variation of the time step with time:

基本培训网上到处都是，还要买吗？

这名字起的，贴的还是大路货，无语！
