Time-Stepping simulation with projections on constraints

class TimeSteppingCombinedProjection : public TimeStepping

#include <TimeSteppingCombinedProjection.hpp>

Time-Stepping scheme.

Public Functions

virtual void initializeOneStepNSProblem() override: initialisation specific to TimeStepping for OneStepNSProblem.

TimeSteppingCombinedProjection(SP::NonSmoothDynamicalSystem nsds, SP::TimeDiscretisation td, SP::OneStepIntegrator osi, SP::OneStepNSProblem osnspb_velo, SP::OneStepNSProblem osnspb_pos, unsigned int _level = 2)

Constructor with the time-discretisation.

Parameters:

nsds – the nsds that we want to simulate
td – a pointer to a timeDiscretisation (linked to the model that owns this simulation)
osi – a one step integrator
osnspb_velo – a one step non smooth problem for the velocity formulation
osnspb_pos – a one step non smooth problem for the position formulation
_level –
