Detailed Description

Specialized class for representing a 6-DOF item for a system, that is a 3D rigid body, with mass matrix and associate variables (a 6 element vector, ex.speed) A full 6x6 matrix is used for the mass matrix, but forces still computed using the "mass" variable of ChVariablesBodyOwnMass

Member Function Documentation

AddMassDiagonalInto()

void chrono::ChVariablesBodyAddedMass::AddMassDiagonalInto ( ChVectorRef result, const double c_a ) const

overridevirtual

Add the diagonal of the mass matrix scaled by c_a, to 'result'. NOTE: the 'result' vector must already have the size of system unknowns, ie the size of the total variables&constraints in the system; the procedure will use the ChVariable offset (that must be already updated) as index.

Definition at line 142 of file ChVariablesBodyAddedMass.cpp.

AddMassTimesVector()

void chrono::ChVariablesBodyAddedMass::AddMassTimesVector ( ChVectorRef results, ChVectorConstRef vect ) const

overridevirtual

Computes the product of the mass matrix by a vector, and set in result: result = [Mb]*vect

Definition at line 119 of file ChVariablesBodyAddedMass.cpp.

AddMassTimesVectorInto()

void chrono::ChVariablesBodyAddedMass::AddMassTimesVectorInto ( ChVectorRef result, ChVectorConstRef vect, const double ca ) const

overridevirtual

Computes the product of the corresponding block in the system matrix (ie. the mass matrix) by 'vect', scale by c_a, and add to 'result'. NOTE: the 'vect' and 'result' vectors must already have the size of the total variables&constraints in the system; the procedure will use the ChVariable offsets (that must be already updated) to know the indexes in result and vect.

Definition at line 131 of file ChVariablesBodyAddedMass.cpp.

Compute_inc_invMb_v()

void chrono::ChVariablesBodyAddedMass::Compute_inc_invMb_v ( ChVectorRef result, ChVectorConstRef vect ) const

virtual

Computes the product of the inverse mass matrix by a vector, and increment result: result += [invMb]*vect

Definition at line 111 of file ChVariablesBodyAddedMass.cpp.

ComputeMassInverseTimesVector()

void chrono::ChVariablesBodyAddedMass::ComputeMassInverseTimesVector ( ChVectorRef result, ChVectorConstRef vect ) const

overridevirtual

Computes the product of the inverse mass matrix by a vector, and set in result: result = [invMb]*vect

PasteMassInto()

void chrono::ChVariablesBodyAddedMass::PasteMassInto ( ChSparseMatrix & mat, unsigned int insrow, unsigned int inscol, const double c_a ) const

overridevirtual

Build the mass matrix (for these variables) scaled by c_a, storing it in 'storage' sparse matrix, at given column/row offset. Note, most iterative solvers don't need to know mass matrix explicitly. Optimized: doesn't fill unneeded elements except mass and 3x3 inertia.
