Includes both the 32 bit and 64 bit executable files for IWFM-2015 (Preprocessor, Simulation, Budget and Z-Budget). These executables are created by Intel Visual Fortran XE 2020 compiler. 64 bit executables have "x64" as part of their filename (e.g. "Simulation2015_x64.exe"). Executables with "D" extension (e.g. "Simulation2015_x64_D.exe") are in debug mode. It is recommended that the executables in debug mode are used when building a model from scratch. Once the model is built and debugged, the executables in release mode (e.g. "Simulation2015_x64.exe") can be used for production.

Executables

Includes the templates for input files that are necessary to run Preprocessor, Simulation, Budget and Z-Budget parts of IWFM-2015.

Templates for input files

Fortran source code for IWFM-2015 that are required to create Preprocessor, Simulation, Budget, and Z-Budget executables. The source code has been compiled and tested using Intel Visual Fortran XE 2020. Microsoft Visual Studio 2017 configuration files have also been included for users interested in compiling the source code using Intel Visual Fortran and building the IWFM executables from scratch. The main configuration file, "BuildAll.sln" solution file, can be found under the folder "BuildAll". This solution file can be opened with Microsoft Visual Studio 2017 and the IWFM executables can be built from scratch. The executables will be saved under the folder "Bin".

Source code

Contains the IWFM input and output files for a sample model. A description of the model is also included.

Sample model

Includes dynamic link library (DLL) for IWFM-2015 that allows software developers interact with IWFM-2015 models directly from their software (e.g. retrieve model results for visualization and analysis tools). The DLL is created by Intel Visual Fortran XE 2020 compiler. The DLL is provided in several versions: both 32 bit and 64 bit versions are available; 64 bit DLLs have “x64” as part of their filenames. DLLs with “D” extension is compiled in debug mode. A “Programmer’s Manual to IWFM-2015” is also included.

IWFM DLL

Themes include wildlife, fire, farmland, land use, renewable energy, geology, recreation.
