CalculateJac()

virtual bool chrono::ChLinkTSDA::ODE::CalculateJac ( double  time, const ChVectorDynamic<> &  states, const ChVectorDynamic<> &  rhs, ChMatrixDynamic<> &  jac, const ChLinkTSDA &  link  )

inlinevirtual

Calculate the Jacobian of the ODE right-hand side with rerspect to the ODE states.

Only used if the link force is declared as stiff. If provided, load df/dy into the provided matrix 'jac' (already set to zero before the call) and return 'true'. In that case, the user-provided Jacobian will overwrite the default finite-difference approximation.

Parameters

time	current time
states	current ODE states
rhs	current ODE right-hand side vector
jac	output Jacobian matrix
link	associated TSDA link

CalculateRHS()

virtual void chrono::ChLinkTSDA::ODE::CalculateRHS ( double  time, const ChVectorDynamic<> &  states, ChVectorDynamic<> &  rhs, const ChLinkTSDA &  link  )

pure virtual

Calculate and return the ODE right-hand side at the provided time and states.

Must load f(t,y).

Parameters

time	current time
states	current ODE states
rhs	output ODE right-hand side vector
link	associated TSDA link

SetInitialConditions()

virtual void chrono::ChLinkTSDA::ODE::SetInitialConditions ( ChVectorDynamic<> &  states, const ChLinkTSDA &  link  )

pure virtual

Set initial conditions.

Must load y0 = y(0).

Parameters

states	output initial conditions vector
link	associated TSDA link
