Simile - computer simulation of complex dynamic systems in the earth, environmental and life sciences

The latest version of Simile, our award-winning simulation and modelling software, is version 5.6 and was released on 22nd December 2009. It is available in three editions to meet all requirements, from evaluation to enterprise-wide model development.

Age-class Model of Population Dynamics, One Compartment Per Age Class

This models a population of animals in terms of four age-classes. For each age-class, we use a compartment (state variable) to represent the number of individuals in that class. In this model, there are four compartments on the model diagram. They are connected by flow arrows, which represent the aging process: the flow of individuals from one class to the next as they get older. Simile allows the same mathematical model to be represented more concisely, using a single compartment embeddedinside a multiple-instance submodel: see the links to other models below.

Age-class Model of Population Dynamics, Using Multiple-instance Submodel

This models a population of animals in terms of four age-classes. For each age-class, we use a compartment (state variable) to represent the number of individuals in that class. This version uses a four-instance submodel to represent the four age-classes. The ageing flow (from one class to the next) thus has to be handled by transferring the value for the outflow from each class to be assigned to the inflow for the next class. In this model, this is done by placing all four outflow values in an array outside the submodel, then selecting the appropriate value from this array for each inflow.

Simile - System Dynamics and object-based modelling and simulation software

Windows version uses latest GUI toolkit allowing models with non-ASCII names to be opened by doubleclicking or dragging. Also, other files referred by the model (parameter metafile and helper setup file) can now open automatically with it if they have non-ASCII characters in their names. Mac version now includes latest GUI toolkit, rather than using older version built in to Mac, reducing crashes. A very rare crash exporting model diagrams as PostScript from the Mac version has been fixed. Various other Mac problems due to ongoing changes to the OS have also been fixed. ARMHF version no longer requires installation of SWI-Prolog
