请教一个ADS momentum仿真的问题
12-10
mesh precompute的时候出现如下warning：
WARNING : Cell size small with respect to pattern.
This may result in a large number of unknowns.
请问这个是我的mesh density设小了还是设大了阿？我现在是30cells/wavelength
WARNING : The ground reference for port 2 is placed at an electrically large
distance from the port. This can cause wrong simulation results.
Consider moving the ground reference closer to the port.
WARNING : The ground reference for port 1 is placed at an electrically large
distance from the port. This can cause wrong simulation results.
Consider moving the ground reference closer to the port.
两个port要相隔多近才没有这个警告阿？
我的mesh frequency是8GHz，仿真的版图整个大概400um*400um的样子吧
谢谢大家：）））

貌似网格过多。通常来说30cell/wavelength应该不会出现这种情况，是不是mesh frequency设置的太大了？
port的问题...是在仿真cpw结构么？把port1and2设置成internal port试试
