Modeling microstrip patch in FDTD with edge port
In the attached CADFEKO file modelling a microstrip line with a defective ground plane using FDTD solver. When I tried to mesh the geometry I get the below error message
I tried defining a local mesh for the geometries where the port 1 and 2 is located, but the number of voxels increases considerably. Can you please look at the model and let me know how to model the structure using FDTD solver

Thanks Torban! This is very helpful. Due to 18 um thickness the MoM solver was very time consuming, so wanted to use FDTD to solve over a band of frequencies. With your suggestion the MoM solver is now considerably faster.

I guess the geometry is just too small for the frequency range and the FDTD mesher. The problems here arise from the 18 µm thick PEC regions. These are not necessary from my point of view, and I have deleted the corresponding faces. Then I refined mesh and so it should work now.
Is there a particular reason you want to use FDTD here?
Best regards,
Torben
