Introduction

Adding Code to the Components

Capsules and components provide the architecture for a runnable simulation; however the computational content needed to relate the these elements and produce results is specified through textual code. In the simplest cases it may only require an elementary mathematical formula. More complex models may need to rely on algorithms specified in a sufficiently expressive language. The Numerus infrastructure aids in model design by predetermining structural relationships and distributing the responsibility for specifying the model's algorithm across a set of well-defined structural elements. In the end, however, some familiarity with textually-specified computations is required. Fortunately, the learning curve need not be steep, and many interesting models requiring minimal coding can be developed.
