At this point, we can launch the simulation. Monostatic analyses require much more time than bistatic cases because the system must be solved for each observation direction. In order to speed up the solution time, we launch the simulation using a workstation with 16 computing cores. A conventional computer is perfectly able to obtain the same results, although requiring longer processing time.
The computed monostatic scattered field for this problem required about 13h and 40m, with an average of 104 iterations to solve each incidence direction using the GMRES solver. The resulting RCS plot is shown in Fig. 9, and can be visualized selecting the Show Results – Far Field – View Cuts option.

Note that for monostatic computations the current visualization plots are not available since for each incident direction there is a different current distribution. In order to visualize the current distribution, a bistatic analysis must be performed.
