APSIMX

APSIM is an agricultural modelling framework that can simulate a variety of biophysical processes for different crops.

VeRCYe relies on the APSIM Next-Gen framework for generating various simulations in a realistic range of input parameters (management practices, soils, water, etc. ).

Installing APSIMX

Visit https://www.apsim.info and make sure you have the proper license.

The below instructions show how to install onto RHEL. This involves * DOTNET installation * Building APSIM from source * Confirming APSIM example runs

export APSIM_SRC_ROOT=/desired/path/to/ApsimX
############################
# DOTNET install

# In future, SAs could install via yum
sudo yum install dotnet-sdk-6.0

# Manual DOTNET install
# Get install script
wget https://dot.net/v1/dotnet-install.sh
