This is an explicit variable-step 4/5-order derivatives method, primarily designed to solve non-stiff and mildly stiff differential equations. Because the method has very low overhead costs, it will usually result in the least expensive integration when solving problems requiring a modest amount of accuracy and having equations that are not costly to evaluate. This simulation algorithm has 4 parameters:
| • | Integration Error (required) |
| • | Absolute: The absolute integration error, valid for every state variable (default: 1e-6). |
| • | Relative: The relative integration error, valid for every state variable (default: 1e-6). |
| • | Step Size (not required) |
| • | Initial: The step size for the first simulation step (default: 0.01). |
| • | Maximum: The maximum size of a simulation step (default: 1). |
