Hi Jim, Thanks for the reply. But I think we are not affordable to use 3D solvers calculating the near field of our main board. So my question here will be how to combine the 3D and 2D EM solvers, but to take the vertical interactions into consideration as well. ( 3D solver for connector EM field calculation, and 2D solver for the main board out of efficiency consideration.) Any suggestion? Thanks!!
