Why there is a sleep function

[Tang115]

Dr. Cui,

When I read the source code in Andes, I see there is a sleep function in TDS.run():
https://github.com/cuihantao/andes/blob/8d484f1ddd02abf71788f2a545c7cbaa152eca73/andes/routines/tds.py#L358

What is the role of this sleep function in TDS. run()? What are we waiting for by setting up this delay?

Best,
Thank you!

Hi,

The sleep function is to implement a so-called quasi-realtime function. It mimics a real-time simulator when the simulation speed is faster than the wall clock speed.

From command line, the quasi-realtime can be tested with andes run case.xlsx -r tds --qrt.
