GEMINI: Download and Install

1. Documentation

• Documentation of the source code of UNIF and GEMINI (limited access)
• Documentation scientifique du modèle GEMINI (limited access)
• Presentation of the UNIF platform

2. Source Code and Software

• Download of UNIF Beta 3
  Contains the source code and the compiled version (for Microsoft Windows) of UNIF. This package is sufficient to simply use UNIF and the GEMINI model.
  This version is the result of the decomposition of UNIF into modules and the review of the code of Canopt.
• Download of UNIF Beta 4 (06-03-01b)
  Contains the source code and the compiled version (for Microsoft Windows) of UNIF. This package is sufficient to simply use UNIF and the GEMINI model.
  This version balances the flux of Canopt.

  - Tilling and senescence are moved out of the automatic integration process.
  - The computation of the nitrate and carbon balances has been corrected.
  - The aerial morphogenesis of grasses has been accelerated.
  - The computation of the senescence rate TSen has been modified.

• Download of UNIF Beta 5 (06-05-12b)
  Contains the source code and the compiled version (for Microsoft Windows) of UNIF. This package is sufficient to simply use UNIF and the GEMINI model.
  This version is the result of the review of the code of Soilopt and the extension of the UNIF plateform.

  - The computation of the immobilization for the LI and WR compartments has been corrected.
  - Modification of the computation of Plantcan::INN.
  - Correction of the computation of Environment::Qn.
  - Correction of the detection of the cut (for the first day).
  - Introduction of variable parameters from data input files.
  - The command-line version is functional.
  - Change of the default value of Plantcan::lwr0.

• Download of UNIF Beta 6 (06-06-12b)
  Contains the source code and the compiled version (for Microsoft Windows) of UNIF. This package is sufficient to simply use UNIF and the GEMINI model.
  This version accelerates the execution of simulations, and keeps running the simulation after the extinction of a population.

  - The integration code with the RK4 method has been modified (runtime divided by 2).
  - The computation of the height of a grass leaf has been replaced (runtime divided by 10).
  - The computation of the Shoots::fracSen method has been modified.
  - The bug identified by Tanja (different behaviors of 16 identical plant populations) has been corrected.
  - The death of a plant does not stop the simulation, the remaining matter is transfered into new compartments (SoilNSen and SoilCSen). These compartments will be used by Soilopt in a next version.
  - New parameters for method CalcSc has been added in Plantcan: Emmc, Emmo, Ejmax and Evcmax.

• Download of UNIF Beta 7 (06-10-09b)
  Contains the source code and the compiled version (for Microsoft Windows) of UNIF. This package is sufficient to simply use UNIF and the GEMINI model.
  This version balances the flux of Soilopt and the Canopt-Soilopt coupling. Maintenance respiration and photosynthesis respect Wohlfahrt 1998.

  - The computation of the nitrate and carbon balances for Soilopt has been corrected.
  - Flux errors in Soilopt has been corrected.
  - The regulation has been modified (this change must be validated !).
  - The Canopt-Soilopt coupling has been corrected: instead of using the derivatives of WcSen and WnSen, the new variables SoilNSen and SoilCSen are used.
  - The computation of the nitrate and carbon balances of the coupling has been corrected.
  - Maintenance respiration and photosynthesis formulas have been changed (Wohlfahrt 1998). Their dependency to temperature has also been modified.

• Download the tools for developing UNIF
  Contains the tools necessary to develop UNIF and GEMINI (e.g. EquaDoc). This archive must be extracted at the same place than the UNIF code (folders beta-x and tools must be at the same place).
• Online access to TeX2PNG
  This tool allows to test the LaTeX code of a mathematical formula and see instantly its rendering. It is very useful when entering the equations in the source code for the EquaDoc tool. An offline version is also available, it is provided in the package of tools for developing UNIF.
• Download CreateSimuFiles
  This tool allows to vary parameter values of a model for sensitivity analysis. It is a console application that creates simulation files (*.gemini.qw) for sensitivity analysis of selected parameters on the basis of a given reference simulation file. In addition, a batch file is generated to launch in one step all the simulations just created.

3. Installation

In order to run the development tools of UNIF, it is necessary to install the following software. You must follow the instructions and install the software at the mentioned places, this way you will avoid the additional step of configuring the tools.

• Minimal Cygwin Environnement (Linux Emulation)
  Extract in C:\Program Files\cygwin_1-5 and execute install.reg.
• Java 2 Development Kit (Java Compilation & Execution)
  Install in C:\Program Files\jdk_1-4-1.
• MiKTeX Software (LaTeX Compilation)
  Install in C:\Program Files\miktex (replace the folder C:\texmf by C:\Program Files\miktex\texmf and the folder C:\localtexmf by C:\Program Files\miktex\localtexmf during the installation step).
• GhostScript Software (PostScript Manipulation)
  Install in C:\Program Files\ghostscript.
