Class TimeSteppingDirectProjection

Defined in Program listing for file kernel/src/simulationTools/TimeSteppingDirectProjection.hpp

class TimeSteppingDirectProjection : public TimeStepping

Time-Stepping scheme with a direct projection onto the constraint thanks to the GGL augmentation of the system.

TimeSteppingDirectProjection(SP::NonSmoothDynamicalSystem nsds, SP::TimeDiscretisation td, SP::OneStepIntegrator osi, SP::OneStepNSProblem osnspb_velo, SP::OneStepNSProblem osnspb_pos, unsigned int _level = 1)

Constructor with the time-discretisation.

  • 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:
