battery_discharge_flag error

[Daniel E.]

Hi all,

I am getting the following error:

AttributeError: 'Conditions' object has no attribute 'battery_discharge_flag'

The following is the mission segment I have setup. I am using a lift_cruise network.

Any thoughts on what could be causing this?

Thank you

Hi Daniel,

This script is missing the unknowns and residuals. Just one line (which is different for each segment) needs to be added.
