Piecewisely linearized outflow function
The simulation of storage elements is carried out with a newly developed module for the calculation of storage elements whose process functions are linear inbetween nodes. This module is based on the approach of Ostrowski (1992)[1] and is described in detail in Mehler (2000)[2]. It allows for the simultaneous solving of the continuity equation for multiple processes without complex iterations and is briefly explained below.
For a storage element whose storage volume depends on several inflow and outflow processes, the continuity equation can be represented as follows:
