net.simplace.client.simulation.lap.sucros.Sucros2

Sim component that implements the Sucros2 algorithm

Description

This sim component implements the crop model Sucros2. For detailed information please consult the original documentation (S).

Changes

The sim component produces the same results as the original FST model (P).

There are no substantial changes in the algorithms. The changes affect the integration into the Simplace framework and renaming of some variables.
