JSim Solvers Page

This page is for the current JSim version 2.0 and higher. Click here for the earlier JSim 1.6 version.


This page describes JSim's numeric solver algorithms and how to control them when running a model. Numeric solvers are available for ordinary and partial differential equations (ODEs and PDEs), linear and non-linear implicit equations, and parameter optimization. JSim provides all solvers with default tuning parameters that are appropriate for most simple problems. However, when equations are particularly challenging or run-time performance particularly critical, users may choose to adjust solver parameters from their default values.

Tuning Guides:

The documents below describe best common practice when tuning solver algorithms for a particular problem.

Reference manuals:

The documents below are exhaustive lists of available algorithms and their tuning parameters.
