HFSS 报错汇总

多层pcb,背地共面波导微带线:

  建模时如下结构:Top+diel1+diel2+diel3+diel4+diel5,参考层都应该在diel内部,否则会出现如下报错:

  [warning] Port refinement, process hf3d: All absorbing boundary conditions have been overridden, this will cause problems in linked projects. (1:00:44 下午 2月 02, 2023)
  [error] Port refinement, process hf3d error: Port 1 does not have a solved inside material on either side.. Please contact ANSYS technical support. (1:00:44 下午 2月 02, 2023)

空气盒子自动设置:

  create region

背地共面波导设置drivenTerminal

  可以加一个0.03空隙的转接块,转接块将平面波导和背地连在一起,然后设置端口。

微带线 drivenTerminal TDR仿真阻抗偏低10-20Ω

  迭代次数默认是6,迭代误差是0.1,大于设置的0.02;加大迭代次数可以让仿真结果逼真!

  SetUp右键,查看收敛情况

微带线 driven Terminal和drivenModel 回损-25dB和-30dB@DC~10GHz

  原因同上?
