Single simulation workflow. From the user perspective, the functional interface to DynaSim involves specifying a model using strings or a DynaSim specification structure, passing it to dsSimulate, and obtaining a DynaSim data structure with the results of simulation. Internally, dsSimulate standardizes the supplied specification using the dsCheckSpecification function. The standardized specification structure is converted into a DynaSim model structure (Figure 7) using the dsGenerateModel function, which adds object-specific namespace identifiers and links variables and functions across model objects (Figure 8). A solve_file for numerical integration is automatically generated from the model structure by dsGetSolveFile according to simulator options. Simulated data is then obtained by evaluating the solve_file. DynaSim structures are shown in bold. Functions are followed by “().” Simulator options are enclosed in parentheses.
