Global variables
Wed, 20/05/2009 - 11:12 — jyearsle
Hi,
Is there a way in Simile to define a global variable (either within a sub-model or across the whole model)?
I could create a variable and put an influence arrow to every variable in the model, but this would end up being a real mess in terms of what the model looked like. The particular model I'm thinking of at the moment is a boolean network model, where each link has a threshold. That threshold is the same for every link in the network.
So I was just wondering if global variables, so that I could bathe every model component in a set of common, fixed, parameters, were supported?
Thanks
Jon

Hi Jon, To reduce clutter
Hi Jon,
To reduce clutter from many influences from one variable, Simile has ghosts, see http://www.simulistics.com/help/diagrams/ghosts.htm (also in the help available from Simile itself).
There is a compromise to make, the influence the ghosted variable has is less apparent. However, this loss can be offset by reducing clutter that can make a diagram difficult to read, never mind unsightly. When analysing the influence network of a diagram with ghosts Simile has some tools to help to trace influences, http://www.simulistics.com/help/diagrams/tracing.htm.
