Member Function Documentation

◆ AddContact() [1/2]

void chrono::ChContactContainerSMC::AddContact ( const ChCollisionInfo cinfo)
overridevirtual

Add a contact between two collision shapes, storing it into this container.

The collision info object is assumed to contain valid pointers to the two colliding shapes. A composite contact material is created from their material properties.

Implements chrono::ChContactContainer.

◆ AddContact() [2/2]

void chrono::ChContactContainerSMC::AddContact ( const ChCollisionInfo cinfo,
std::shared_ptr< ChContactMaterial mat1,
std::shared_ptr< ChContactMaterial mat2 
)
overridevirtual

Add a contact between two collision shapes, storing it into this container.

A compositecontact material is created from the two given materials. In this case, the collision info object may have null pointers to collision shapes.

Implements chrono::ChContactContainer.

◆ ArchiveIn()

void chrono::ChContactContainerSMC::ArchiveIn ( ChArchiveIn archive_in)
overridevirtual

Method to allow de-serialization of transient data from archives.

Method to allow de serialization of transient data from archives.

Reimplemented from chrono::ChContactContainer.

◆ BeginAddContact()

void chrono::ChContactContainerSMC::BeginAddContact ( )
overridevirtual

The collision system will call BeginAddContact() before adding all contacts (for example with AddContact() or similar).

Instead of simply deleting all list of the previous contacts, this optimized implementation rewinds the link iterator to begin and tries to reuse previous contact objects until possible, to avoid too much allocation/deallocation.

Reimplemented from chrono::ChContactContainer.

◆ ComputeContactForces()

void chrono::ChContactContainerSMC::ComputeContactForces ( )
overridevirtual

Compute contact forces on all contactable objects in this container.

This function caches contact forces in a map.

Reimplemented from chrono::ChContactContainer.

◆ EndAddContact()

void chrono::ChContactContainerSMC::EndAddContact ( )
overridevirtual

The collision system will call BeginAddContact() after adding all contacts (for example with AddContact() or similar).

This optimized version purges the end of the list of contacts that were not reused (if any).

Reimplemented from chrono::ChContactContainer.

◆ IntLoadResidual_F()

void chrono::ChContactContainerSMC::IntLoadResidual_F ( const unsigned int  off,
ChVectorDynamic<> &  R,
const double  c 
)
overridevirtual

Takes the F force term, scale and adds to R at given offset: R += c*F.

Parameters
offoffset in R residual
Rresult: the R residual, R += c*F
ca scaling factor

Reimplemented from chrono::ChPhysicsItem.

◆ LoadKRMMatrices()

void chrono::ChContactContainerSMC::LoadKRMMatrices ( double  Kfactor,
double  Rfactor,
double  Mfactor 
)
overridevirtual

Compute and load current stiffnes (K), damping (R), and mass (M) matrices in encapsulated ChKRMBlock objects.

The resulting KRM blocks represent linear combinations of the K, R, and M matrices, with the specified coefficients Kfactor, Rfactor,and Mfactor, respectively. Note: signs are flipped from the term dF/dx in the integrator: K = -dF/dq and R = -dF/dv.

Reimplemented from chrono::ChPhysicsItem.

◆ Update()

void chrono::ChContactContainerSMC::Update ( double  mtime,
bool  update_assets = true 
)
overridevirtual

Update state of this contact container: compute jacobians, violations, etc.

and store results in inner structures of contacts.

Reimplemented from chrono::ChPhysicsItem.
