◆ initialize()

int ParticleCollision::initialize ( const shared_ptr< DomainBase > & D )

overridevirtual

Reimplemented from ConditionalModifier.

Here is the call graph for this function:

◆ process()

int ParticleCollision::process ( const shared_ptr< DomainBase > & )

overridevirtual

Process and update both stiffness and resistance.

This method provides all necessary pieces of typical constraints/loads required, including additional blocks in original global stiffness, border matrix resistance of multiplier, external loads.

Implements ConditionalModifier.

Here is the call graph for this function:

◆ process_meta()

virtual int ParticleCollision::process_meta	(	const shared_ptr< DomainBase > &	,
		bool
	)

Here is the caller graph for this function:

◆ process_resistance()

int ParticleCollision::process_resistance ( const shared_ptr< DomainBase > & D )

overridevirtual

Process and update resistance.

For some algorithms, the global stiffness is formed only once in each substep. After calling solver, the storage may contain factorization. It is not correct to modify it in those algorithms. This method should provide updated constraint/load resistance but must not touch global stiffness.

Reimplemented from ConditionalModifier.
