Dear Petia,
this looks a lot like you run out of working memory (RAM) on your machine. You can check the memory consumption by adding
print('Memory before Simulate():', nest.ll_api.sli_func('memory_thisjob')
right before your call
Simulate(). The printed number is in kiB
I am afraid that we can’t do much else for you here.
Best regards,
Jochen!
