Hi everyone, I have encountered unexpected issue when running repeated FDTD 2D simulation using matlab. <\/p>\n

I tried to run the following code from matlab (I have ignored here the loading of the .fsp file)<\/p>\n

The structure and simulation setup code is written inside the "model" object, not in a separate .lsf script file. <\/p>\n

ideally this should run the same simulation multiple times (5 times here). this might seem purposeless but what I am doing is trying to narrow down the cause of my optimization error and I think fundamentally this is the cause. <\/p>\n

Lumerical would successfully run the first simulation (some times up to the third simulation). But then it will give the following error as shown in the screenshot. <\/p>\n

However, if I implement this for loop (basically just switchtolayou; run;) directly in a .lsf file, it seems no error would pop up and Lumerical would finish all five simulations. Due to the use of optimization, I have to interface with matlab. <\/p>\n
