Tips for debugging

Co-simulations can be tricky to debug. Here are some tips to debugging a co-simulation.

• Always print current time granted.
• Use h.HELICS_FLAG_TERMINATE_ON_ERROR flag for all federates.
• Check HELICS_FEDERATE_STATE to ensure that the federate is doing what you expect it to.
• Set HELICS_LOG_LEVELS to show all messages.
• Sometimes force quiting a co-simulation is necessary. You may need to use killall python, kill -9 $pid, kill %1.
