wave port与lumped port,delta s设置含义不太清楚

wave port与lumped port它们的设置含义
Delta S
The Delta S is the default criteria used to determine mesh/solution
convergence. The Delta S is defined as the maximum change in the
magnitude of the S-parameters between two consecutive passes:
这里英文解释还是有点迷糊
请高手赐教！

本站里有解释这两个端口的含义及应用情况，楼主自己搜一搜

The Delta S is the default criteria used to determine mesh/solution m/cbRuPWgP
convergence. The Delta S is defined as the maximum change in the * 8kg6v%
magnitude of the S-parameters between two consecutive passes
ds是收敛参数，即每次频率解析时，要重新设定收敛因子。
