Special Solver Parameters - Steady State
Maximum solver duration 最大求解时间
Here, the maximum simulation time of the solver run can be defined. This means that the simulation will stop after a certain time, which can be defined in three different ways.
在这里，可以定义求解器运行的最大模拟时间。这意味着模拟在一定时间后会停止，可以用三种不同的方式定义。
However, often the simulation time will not reach these limits. It may be stopped earlier automatically by the steady-state test. The accuracy for this test is set in the solver dialog box. This test considers the energy decay as well as the decay of the port mode amplitudes. In addition custom stop criteria can be defined as described in the section below.
然而，往往模拟时间不会达到这些限制。它可能会被稳态测试自动提前停止。这个测试的精度是在求解器对话框中设置的。该测试考虑了能量的衰减以及端口模式振幅的衰减。此外，还可以定义自定义的停止标准，如下面一节所述。
Number of pulses: Here, the simulation duration is calculated by multiplying the given number with the Gaussian pulse width that is used as stimulation signal. This pulse width depends on the frequency range of the reference excitation signal.
在这里，模拟持续时间是通过将给定的数字与用作激励信号的高斯脉冲宽度相乘来计算的。这个脉冲宽度取决于参考激励信号的频率范围。
Please note: In case of non-Gaussian excitation signals (e.g. rectangular) with a given total time (Ttotal) this value prevails and determines the simulation duration. Similarly, in case of a transient co-simulation the simulation time is given by the setting of Tmax for the transient task. In both cases however, if a nearfield source excitation is used, the simulation time might be extended in order to correctly cover its input signal. If this happens an appropriate info message is generated.
Time: This number directly defines the maximum simulation time. 直接定义最大仿真时间。
Propagation distance: This number is used to describe the maximum simulation time via a length setting. The value will by divided by the speed of light.
这个数字用于通过长度设置来描述最大的模拟时间。该值将被光速相除。
Default: Pressing this button resets the Maximum solver duration to its default value. This corresponds to 20 pulses for the Number of pulses setting. The default value for the Propagation distance and Time settings corresponds to 20 times the maximum length (among the x, y and z axis) of the model bounding box and to the time spam required by an electromagnetic wave to travel it, respectively.
