◆ 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)

◆ 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 .
