OpenSim::MocoSolver Class Reference

Description

Once the solver is created, you should not make any edits to the MocoProblem.

If you do, you must call resetProblem(const MocoProblem& problem).

(

)

const

(Experimental) Run a forward simulation (using the OpenSim Manager, which uses a SimTK::Integrator), using the default controls for actuators and the default states as the initial states, to create a guess that is dynamically consistent (constraint errors should be small).

The time range for the simulation is the upper bound on the initial time and the lower bound on the final time. The initial state values are the default state values unless:

• initial bounds are an equality constraint: use the bound value
• default value is not within the initial bounds: use midpoint of initial bounds.

The number of times in the iterate is the number of successful integration steps.

Note

This function does not yet support problems with parameters.

Exceptions

Exception

If the lower bound on the final time is less than or equal to the upper bound on the initial time. This situation is okay in general; it's just that this function doesn't support it.

Precondition(s):

You must have called resetProblem().

setSolutionStats()

static void OpenSim::MocoSolver::setSolutionStats ( MocoSolution &  , bool  success, double  objective, const std::string &  status, int  numIterations, double  duration  )

This is a service for derived classes, because MocoSolution::setStatus(), MocoSolution::setSuccess(), etc.

are private but this class is a friend of MocoSolution.
