int rolling_fc2d_compute_error(RollingFrictionContactProblem *problem, double *z, double *w, double tolerance, SolverOptions *options, double norm, double *error)

Error computation (using the normal map residual) for rolling friction-contact 2D problem.

Parameters:

• problem – the structure which defines the friction-contact problem

• z – vector

• w – vector

• tolerance – value for error computation

• options –

• norm – norm of a vector (problem->q) for relative error

• error – [inout] value

Returns:

0 if ok

void rolling_fc2d_unitary_compute_and_add_error(double r[3], double u[3], double mu, double mur, double *error, double *worktmp)

Error computation (using the normal map residual) for one rolling friction-contact 2D problem.

Parameters:

• r – the reaction force

• u – the local velocity

• mu – coeficient of friction

• worktmp – work vector

• error – [inout] value
