Transport Units
Transport are a multipurpose unit.
They can represent almost every processing step, which is characterized by negligible deformation but by thermal flows or microstructure evolution.
The most used application is the cooling in the clearances between every roll pass.
But, also furnaces or cooling ranges can be described by transport units.
In future, there may be dedicated specialized unit types to represent such aggregates.
Transports are represented by the Transport class.
Create a Transport object as follows:
Transport(
duration=10,
...
)
The hook Transport.duration is the most important property of a transport.
It defines the temporal extent of the transport.
An alternative way of defining the extent is a combination of the spatial extent Transport.length and the material flow velocity.
Transport(
length=10,
velocity=1, # can be left out if known from the in profile
...
)
However, this approach may not be appropriate for all transports, as the velocity may not be constant or the spatial extent may be meaningless. Therefore, all models for transport are recommended to be defined at the timescale and independent of the length scale, if possible.
