Ecolego is a powerful and flexible software tool for creating dynamic models and performing deterministic or probabilistic simulations. Ecolego can be used for conducting risk assessments of complex dynamic systems evolving over time with any number of species. Ecolego has specialised databases and other add-ons designed for the field of radiological risk assessment.
Easy management of blocks, parameters, materials and other settings.
Hierarchical containers facilitates construction and documentation of large and complex models.
Projects are easily managed using the project browser, which displays a hierarchical view of blocks, parameters, contaminants and other objects. Multiple projects can be open simultaneously
Copy-paste of parameters, containers, blocks and materials within and between projects.
Tool tips present information about selected objects, such as equations, units, “used by” or “uses” relationships.
Hyperlinks allow the user to jump to different parts of the model.
Creation of models using interaction matrices
Sub-system modules can be created to create re-usable components
Documentation of models using images, hyperlinks, categories, units and comments
Parameters and blocks can be created on-the-fly while equations are written
Listings of all undefined objects or illegal values
Generates full reports that can be saved in many different formats including the Adobe PDF format
