Realtime mode stops when no clock is specified

dchassin commented 1 year ago

Problem description

The simulation does not enter realtime mode when requested.

Steps to reproduce

Do the following:

$ gridlabd model get IEEE/123
$ gridlabd -D run_realtime=1 123.glm
WARNING  [INIT] : node_14: substation:3 is using the default base power of 100 VA. This could cause instability on your system.
WARNING  [2023-05-19 06:15:46 PDT] : last warning message was repeated 26 times
$

Expected behavior

The simulation should not exit.

The reason is that the IEEE/123 does not contain anything that would change over time, so the simulation goes immediately to steady state and stops. The immediate solution is to include weather data. The long-term solution is to add global variable to control the default behavior so that the simulation does not stop on steady state.

Another solution is to change the default stop behavior when running in realtime to not stop on steady state.
