Hello all,
I am having trouble simulating my antenna, not due to errors but because of the time it is taking to create the mesh. I had the simulation running last night for 6 hours and it didn't seem to get very far.
The model is basically this slow because I have a 10 metre by 10 metre airbox surrounding the antenna set as the radiation boundary. It is this big because I am working at around 13 MHz and I read in other posts that the boundaries should be at least 1/4 λ from the antenna. Is this correct?
I have also heard about using PMLs because it may mean a quicker solution but I am not sure hw to use PMLs
Can anyone tell me what I am doing wrong?
Can anyone explain how to use PML boundaires instead? do I still need such a large airbox?
Thanks
