Overview of supported Algae models
Models supporting biomass transfer can be instructed to move a fixed amount of biomass to a new medium after a period of time. This feature replicates a procedure occurring in e.g. Lemna effect studies and may be necessary to recreate study results.
The biomass transfer feature assumes that always a fixed amount of
biomass is transferred. Transfers can occur at any fixed point in time or
in regular intervals. During a transfer, the biomass is reset to the
transferred amount and additional compartments can be scaled 1:1 accordingly,
to e.g. reflect the change in internal toxicant mass when biomass is modified.
Transfer settings can be modified using set_transfer().
If a transfer occurs, simulation results of that time point will report the model state
before the transfer. Be aware that if transfers are defined using the
interval argument, the transfers will always occur relative to time point
zero (t = 0). As an example, setting a regular transfer of seven days,
interval = 7, will result at transfers occurring at time points which are
integer multiplicates of seven, such as t=0, t=7, t=14 and so forth.
The starting and end times of a scenario do not influece when a regular
transfer occurs, only if it occurs.
