I used the trial version of FDTD solution. Sometimes when I start the run button, the software cannot start multi-threads computing. Each time I need quit the simulation and restart it again and again till it triggers the multi-cpu. I donot know if this is problem of trial version or other problems.
Additional question, during the simulation, normally software shows the aprroximate simulation time, however, in my most case, my simulation stops much earlier before the suggested time. The reason for me is alway multi-threads computing stops after starting several minutes. I donot know, it is problem of my computer or trial problem or setting of my cases.
I use FDTD solution to simulate the scattering from metallic grating with area about 5 µm * 5 µm.
Thank you very much in advance.
