New release: GLEaMviz Simulator v2.8
We are pleased to announce the release of GLEaMviz Simulator v2.8. The principal new feature in this release is the ability to specify time-dependent overrides of the default values for variables defined in the compartmental model. Such overrides can be used to model time-dependent changes in the infection dynamics of the epidemic such as the effect of mitigation policies on the disease parameters.
A new panel in the Simulation Wizard, shown in the figure below, enables the modeler to add one or more time-dependent variable overrides. Each override applies for one selected variable and is valid from the selected start date up to and including the selected end date. The overriding value is specified as an algebraic expression that may include references to other variables, just like a default value for variables or transition rates expressions.
Starting from this release it is now also possible to use parenthesis in such expressions.
