The IONTW simulation tool

IONTW uses the NetLogo programming language, which was developed by Uri Wilensky at the The Center for Connected Learning and Computer-Based Modeling.

IONTW simulates both discrete and continuous time agent-based models of infectious disease dynamics on networks. It can simulate models of type SEIR, SIR, SEI, SI, SEIS, and SIS. 
Supported network types include: complete graphs, empty graphs, Erdös-Rényi, nearest-neighbor (1 and 2 dimensions), small world (1 and 2 dimensions), preferential attachment, generic scale-free, spatially clustered, random regular, trees, as well as approximately uniform realizations from custom degree sequences and custom distributions.
The Reference Guide that is included with the software package gives detailed instruction on how to enforce these and other options.

The following presentation gives a more detailed overview of IONTW's capabilities:
