fedoo.time.CentralDifference

class CentralDifference

Explicit central-difference integrator.

This is the explicit Newmark specialization beta=0 and gamma=1/2 without generalized-alpha filtering.

Methods

CentralDifference.acceleration(...)	Convert the mass-solve result into the end-step acceleration.
CentralDifference.compile_assembly(assembly)	Register assembly-level storage while keeping static weakforms.
CentralDifference.compile_weakform(weakform)	Return a time-integrated version of weakform when applicable.
CentralDifference.correct(state, ...)	Return the corrected end-step state.
CentralDifference.effective_mass_factor(dt)	Return the coefficient multiplying mass in the displacement solve.
CentralDifference.enforce_displacement(...)	Impose displacement values and update constrained kinematics.
CentralDifference.evaluation_state(state, ...)	Return displacement and velocity used to evaluate forces.
CentralDifference.mass_history(state, ...)	Return the known kinematic vector multiplied by mass on the RHS.
CentralDifference.predict(state, dt)	Return predicted displacement and velocity.
CentralDifference.prepare_step(state, dt)	Evaluate centered-difference forces at the current state.
CentralDifference.state_from_displacement(...)	Return the end-step state from the solved displacement.

CentralDifference.evolution	TimeEvolution category handled by this integrator (set by subclasses).
