Downloading the code implies agreement to these conditions.
1. SEIB-DGVM can be used by any researchers and by any organs for research purpose. For other usage, please contact to Dr Hisashi SATO and obtain permission beforehand.
2. The code is provided with no guarantees as to the accuracy, correctness or utlility of the output produced.
3. Modified code can be only redistributed with permissions of Dr Hisashi SATO.
4. Publications should give adequately citation to the authors of the SEIB-DGVM (see Publications page). We really appreciate if you send us resultant publications!
Program language is Fortran90. Currently, only Japanese versions (i.e., readme.txt is written in Japanese only) are available.
SEIB-DGVM Distribution Packages
The distributed code is point simulation version; it simulates only single virtual forest (grass land). The setting area of the virtual-forest is 30mx30m, but it can be easialy changed by modifing the configuration file. For simulation of multule plot (regional scale or global scale), a recent super computer will be required.

SEIB-Explorer
This is a Windows software designed to "realistically" visualize forest dynamics output from a single location simulated by SEIB-DGVM (file name: output_forest.txt). While the simulation in SEIB-DGVM assumes cylindrical shapes for canopies and trunks, this software focuses on visual enjoyment and engagement by providing a more "realistic" representation. The software is intended primarily for educational and presentation purposes rather than research.
Additionally, this software includes a "Simplified View" feature that represents the tree shapes assumed in the model. However, please note that the cylindrical representation of trees displayed in this view does not accurately match the numerical values or sizes in the simulation file. When creating figures for academic publications, please use the PovRay code (extension "pov") included with the simulation code.
