Dear experts,
I would like to ask a few simulation questions.
1. For an array size of 8 wavelengths × 8 wavelengths, can we use a frequency-domain solver to simulate and obtain the far-field radiation pattern?
2. Currently, I am using frequency-domain simulation with a mesh division of 4.2 million grids and adaptive meshing. However, it is stuck at pass1: direct solve run 67%.
3. The phase response of each element is obtained through frequency-domain simulation and modeled accordingly. Will there be any error in the results if I simulate the array using the time domain?
