APSIM next generation

Over 24 years, the Agricultural Production Systems sIMulator (APSIM) has grown from a farming systems framework used by a small number of people, into a large collection of models used by many thousands of modellers internationally. The software consists of many hundreds of thousands of lines of code in multiple programming languages. This infrastructure has successfully integrated a diverse range of models but isn’t capable of easily meeting new demands from modellers. For these reasons, the APSIM Initiative has begun developing a next generation of APSIM (dubbed APSIM next generation) that is a completely new application with no legacy code and designed to run across different platforms. Currently APSIM next generation has limited capability and isn’t quite ready for mainstream use. However, if your modelling problems fits within the specified capability, or you simply wish to evaluate this release, then it can be downloaded from the APSIM registration page (look for ‘next generation’ in the version drop down box).
