def append_cryogenic_tank_conditions(cryogenic_tank, segment, bus):
"""
Appends conditions data structure to cryogenic tank component for use during mission analysis.
Parameters
----------
cryogenic_tank : CryogenicTank
The cryogenic tank component for which conditions are being initialized.
segment : Segment
The mission segment in which the cryogenic tank is operating.
bus : Bus
The energy bus connected to the cryogenic tank.
Returns
-------
None
Notes
-----
This function initializes the conditions for a cryogenic tank component at the start
of a mission segment. It creates a Conditions object for the cryogenic tank within
the segment's energy conditions dictionary, indexed by the bus tag and tank tag.
The function initializes arrays for:
- Mass flow rate [kg/s]
- Mass [kg]
These arrays are initialized with ones of the same length as the segment's state vector,
which will be updated during mission analysis based on the cryogenic tank's performance
and usage.
