Detailed Description

Contains the data needed for AST formula evaluation and odeModel integration and usually corresponds to an odeModel.

cvodeData is used for storing current variable, sensitivity and time values. It also holds the internal version of ODEs for optimized for a specific integration run and current (on or off) states of event triggers and of steady state approximation and the number of integration runs with this instance of cvodeData.

API Interface functions to retrieve values directly from cvodeData, instead of via IntegratorInstance_getVariableValue()) will be available in one of the next releases!
