How can simulation be fast when Electric Field is being measured with probe in CST Microwave Studio? [closed]

I am measuring the electric field in the closure box with aperture and using probe to achieve that. But I have a problem. When I use the probe for measurement, results are not accurate in transient ...

Defining electric current source excitations for surface integral equation formulations

In a finite difference (FD) based electromagnetic formulation based on a Yee cell grid, one can define electric current source excitations ($J$) on the $E$ field grid points. At a distance, the fields ...
