◆ InjectVariables()

void chrono::ChBodyAddedMass::InjectVariables ( ChSystemDescriptor &  mdescriptor)
overridevirtual

Tell to a system descriptor that there are variables of type ChVariables in this object (for further passing it to a solver)

Definition at line 97 of file ChBodyAddedMass.cpp.

ChVectorDynamic<> &  R,
const double  c 
)
overridevirtual

Definition at line 171 of file ChBodyAddedMass.cpp.

ChVectorDynamic<> &  R,
const ChVectorDynamic<> &  w,
const double  c 
)
overridevirtual

const ChStateDelta &  v,
const ChVectorDynamic<> &  R,
const unsigned int  off_L,
const ChVectorDynamic<> &  L,

Definition at line 18 of file ChBodyAddedMass.cpp.

◆ SetInertiaXX()

void chrono::ChBodyAddedMass::SetInertiaXX ( const ChVector<> &  iner)

◆ SetInertiaXY()

void chrono::ChBodyAddedMass::SetInertiaXY ( const ChVector<> &  iner)

Definition at line 31 of file ChBodyAddedMass.cpp.

◆ SetInvMfullmass()

void chrono::ChBodyAddedMass::SetInvMfullmass ( ChMatrixDynamic<>  inv_Mfullmass_in)

◆ SetMass()

void chrono::ChBodyAddedMass::SetMass ( double  newmass)

Definition at line 13 of file ChBodyAddedMass.cpp.

◆ SetMfullmass()

void chrono::ChBodyAddedMass::SetMfullmass ( ChMatrixDynamic<>  Mfullmass_in)

Definition at line 58 of file ChBodyAddedMass.cpp.

◆ Variables()

Definition at line 26 of file ChBodyAddedMass.h.

◆ VariablesFbIncrementMq()

void chrono::ChBodyAddedMass::VariablesFbIncrementMq ( )
overridevirtual

Adds M*q (masses multiplied current 'qb') to Fb, ex. if qb is initialized with v_old using VariablesQbLoadSpeed, this method can be used in timestepping schemes that do: M*v_new = M*v_old + forces*dt

Definition at line 117 of file ChBodyAddedMass.cpp.

◆ VariablesFbLoadForces()

void chrono::ChBodyAddedMass::VariablesFbLoadForces ( double  factor = 1)
overridevirtual

Adds the current forces applied to body (including gyroscopic torque) in encapsulated ChVariablesBody, in the 'fb' part: qf+=forces*factor

Definition at line 106 of file ChBodyAddedMass.cpp.

◆ VariablesFbReset()

void chrono::ChBodyAddedMass::VariablesFbReset ( )
overridevirtual

Definition at line 102 of file ChBodyAddedMass.cpp.

◆ VariablesQbIncrementPosition()

void chrono::ChBodyAddedMass::VariablesQbIncrementPosition ( double  step)
overridevirtual

Increment body position by the 'qb' part of the ChVariablesBody, multiplied by a 'step' factor. pos+=qb*step If qb is a speed, this behaves like a single step of 1-st order numerical integration (Eulero integration). Does not automatically update markers & forces.

Definition at line 147 of file ChBodyAddedMass.cpp.

◆ VariablesQbLoadSpeed()

void chrono::ChBodyAddedMass::VariablesQbLoadSpeed ( )
overridevirtual

Initialize the 'qb' part of the ChVariablesBody with the current value of body speeds. Note: since 'qb' is the unknown, this function seems unnecessary, unless used before VariablesFbIncrementMq()

Definition at line 121 of file ChBodyAddedMass.cpp.

◆ VariablesQbSetSpeed()

void chrono::ChBodyAddedMass::VariablesQbSetSpeed ( double  step = 0)
overridevirtual

Fetches the body speed (both linear and angular) from the 'qb' part of the ChVariablesBody (does not updates the full body&markers state) and sets it as the current body speed. If 'step' is not 0, also computes the approximate acceleration of the body using backward differences, that is accel=(new_speed-old_speed)/step. Mostly used after the solver provided the solution in ChVariablesBody .
