file simulates a accelerostat (Astat) in which the dilition rate
constantly increases with time. The kinetic models used here are
approximately the same as those in fedbatch_Cmole. With the parameters
used in this simulation, my=D except at high dilution rate.
models are used, which do not take into account the intracellular
changes caused by the changed growth rate. Therfore it can not be
concluded that true steady-state exists even when my=D.
