Implicit time integrator which conserves linear momentum and mechanical energy

Data:

  • name : object name

  • printLog : if true, emits extra messages at runtime.

  • tags : list of the subsets the objet belongs to

  • bbox : this object bounding box

  • componentState : The state of the component among (Dirty, Valid, Undefined, Loading, Invalid).

  • listening : if true, handle the events, otherwise ignore the events

  • newtonError : Error tolerance for Newton iterations

  • steps : Maximum number of Newton steps

  • rayleighMass : Rayleigh damping coefficient related to mass, > 0

  • saveEnergyInFile : If kinetic and potential energies should be dumped in a CSV file at each iteration

  • explicitIntegration : Use explicit integration scheme

  • file : File name where kinetic and potential energies are saved in a CSV file

  • computeHamiltonian : Compute hamiltonian

  • hamiltonianEnergy : hamiltonian energy

  • useIncrementalPotentialEnergy : use real potential energy, if false use approximate potential energy
