Writing JSim Models
The documents below provide information on how to write JSim models. JSim models are written in JSim's own Mathematical Modeling Language(MML), an easy-to-read text-based language. MML models are most often expressed in terms of mathematical equations (for example, ordinary or partial differential equations), but formulation via discrete events and function calls to Java, C and Fortran are also available. MML is constructed so that model writers may intermix mathematics, events and procedural code as needed.
Basic MML
Specific MML Topics
- Built-in constants, operators & functions
- Ordinary differential equations
(ODEs)
- Partial differential equations (PDEs)
- Integrals & Summations
- Implicit Equations
- Events (discrete state changes)
- Functions & Procedures (embedded Java, C, Fortran)
- Templates (reusable model components)
- Miscellaneous short topics
