Detailed Description

Abstract base class for contact search algorithms.

The ContactSearch class defines a common interface for algorithms responsible for detecting potential contact interactions between contact surfaces. It provides the functionality required to identify candidate contact pairs based on geometric proximity, bounding-box intersection, or other search strategies.

Concrete implementations may employ different search techniques, such as brute-force search, spatial partitioning, hierarchical bounding volumes, or grid-based methods. The output of a contact search is typically a set of potential contact pairs that can be further processed by contact enforcement algorithms.

This class focuses solely on contact detection and does not prescribe any particular contact formulation or constraint enforcement method.

Member Function Documentation

createContactPairs()

virtual void oofem::ContactSearchAlgorithm::createContactPairs ( )

pure virtual

Creates initial contact pairs based on the current configuration.

Performs broad-phase (and possibly narrow-phase) detection to produce a set of candidate contact pairs used by the contact boundary condition.

Implemented in oofem::ContactSearchAlgorithm_Surface2FESurface.

getContactPairs() [1/2]

std::vector< std::unique_ptr< ContactPair > > & oofem::ContactSearchAlgorithm::getContactPairs ( )

inline

Returns the internally stored list of contact pairs.

Definition at line 96 of file contactsearch.h.

References contactPairs.

getContactPairs() [2/2]

const std::vector< std::unique_ptr< ContactPair > > & oofem::ContactSearchAlgorithm::getContactPairs ( ) const

inline

Returns the internally stored list of contact pairs (const overload).

Definition at line 100 of file contactsearch.h.

References contactPairs.

updateContactPairs()

virtual void oofem::ContactSearchAlgorithm::updateContactPairs ( TimeStep * tStep )

pure virtual

Updates previously created contact pairs for the current time step.

Typical responsibilities include re-projection, pair filtering, and updating kinematic measures (gap, normals, tangents) as the configuration changes.

Parameters

tStep

Current time step.

Implemented in oofem::ContactSearchAlgorithm_Surface2FESurface, oofem::ContactSearchAlgorithm_Surface2FESurface_2d, oofem::ContactSearchAlgorithm_Surface2FESurface_3d, and oofem::ContactSearchAlgorithm_Surface2FESurface_3d_SweepAndPrune.
