I know that the simulation must within the grid that I defined in advance.But if my simulation in a large radius,100mm,for instance,with a small sample in the center.If I must define a grid with a width larger than 200mm?If so,the simulation speed will be very very slow for a acceptable visual.Or I can local reconstruct the large region with my sample included?Thank you in advance.

Hi ImmortalAvatar,
I'm not sure I follow your question. In general, yes, the grid must be large enough to encompass the source and the sensor. If your source is a long way away in free-field, one option might be to first use the Rayleigh integral or angular spectrum to project it closer to the sensor.
Hope that helps,
Brad.
