### What is different with **ORCHESTRA**?

**ALL **model equations are given as input in text format at run time, so **NO** model equation hidden in the source code.
- The structure of model definitions is
**hierarchical** and **Object Oriented**.
- Users can construct new models by
**defining new model objects** and **keywords**.
- ORCHESTRA is written in
**Java** and runs on Windows, Linux, Solaris, and Apple OSX.

### What are the advantages?

**ORCHESTRA** is very **flexible** as it can easily be extended with new chemical physical biological process models.
- The physical separation of calculation solver and model definitions not only results in a
**small** and **efficient** calculation solver executable (350 kb)
- but also in very
**compact model definitions** (object database 30 kb).
- Model calculations are
**transparent**, as all model equations are available in text format and not hidden within the source code.
- The small size of the calculation solver makes it very suitable for parallel processing on modern multi core hardware.
