This version and input files work with 2DSOIL version 3.1.2.0 and Maizsim version 1.8.1 (uploaded 9/23/2025)
An excel based interface to create the input files needed for the crop models The input data are stored in an excel spreadsheet. A special Excel file contains VBA code to pull data from the spreadsheet and create the folder structure and input files needed to run maizsim. The VBA program generates grid1.bat files in each folder that will create the grid and soil files when run. Only the weather files are not created.
the Models folder has the executables
Working examples include data for Kansas dryland (paper in progress), Maryland Eastern Shore (published in Kim et al., 2012) and AgmipET2 from a paper by Kimball et al, https://doi.org/10.1016/j.agrformet.2023.109396
5/23/2024 Newly added are the input and output files for maizsim where we published tests of the CO2 model in Geoderma 1/30/2026 Added files for a comparision of maizsim for a topical and temperate location - paper in review
To run the model, use the root folder set in the excel interface. let's say the root is d:/agmipet2 and under this are the data folders, run_01 and run_02 then the executables would go into the agmipet2 folder and you would run the model as d:/agmipET2 > 2dmaizsim ./run_01/runrun01.dat
if you use the folder structure in this repository: Y:\ExcelInterface you would run the model as: 2dmaizsim ./"Example input/agmipET2/run_01/runrun_01.dat" Your files would be set up this way in the interface: Input excel file: Y:\ExcelInterface\Example input\AgmipET2\AGMIPET2Sim.xlsx Root Path: Y:\ExcelInterface\Example input\AgmipET2 MaizsimPath Y:\ExcelInterface CreateSoils Y:\ExcelInterface\CreateSoilFIles ExcelInterface Y:\ExcelInterface\ExcelInterface Weather CSV File Folder Y:\ExcelInterface\Example input\AgmipET2
