Hello Jia,
this is number 81 in a series of calculations, run in a normal windows command prompt. At number 81 the output in the prompt stopped. But indeed, if I wait long enough, the calculation converges.
Please excuse my impatience. 🙂
In fact, we encounter numerical problems every once in a while, but usually epsilon, delxi, or pickup entire are our friends.
Best regards,
Helge
