Welcome to Simulistics

System Dynamics and object-based modelling and simulation software

Simile version 7.1 released.

Simulistics develops and distributes Simile, modelling and simulation software for complex dynamic systems in the earth, environmental and life sciences. We use unique logic-based declarative modelling technology to represent the interactions in these systems in a clearly structured, visually intuitive way.

Using Simile makes modelling a more productive task for scientific investigators. Models can be prepared more quickly, shared more easily and maintained more efficiently.
Quicker than writing C++ or Fortran code
More expressive than other visual modelling software
Better structured than a spreadsheet

Simile has a System Dynamics heart, like many other visual modelling and simulation software tools. However, with Simile, you also benefit from the following features:

  • Object-based representation, for handling disaggregation and individual-based modelling
  • Discrete events and rule-driven state variables seamlessly integrated with system-dynamics operation
  • Auto-generated C++ model code, for fast execution
  • Plug-and-play modules, supporting modular modelling, any part of a model can be extracted and used separately
  • Plug-in displays, allowing you to create graphics specific to your field
  • Declarative model representation, making it easy to manipulate the model in complex ways
