Typedef and functions declarations related to Newton solver for 3 dimension frictional contact problems.

Each solver must have 4 functions in its interface:

  • initialize: link local static variables to the global ones (M,q,…)

  • update: link/fill the local variables corresponding to sub-blocks of the full problem, for a specific contact

  • solve: solve the local problem

  • free

Typedefs

typedef void (*computeNonsmoothFunction)(double*, double*, double, double*, double*, double*, double*)#

Functions

void fc3d_onecontact_nonsmooth_Newton_solvers_initialize(FrictionContactProblem *problem, FrictionContactProblem *localproblem, SolverOptions *options)#

initialize friction-contact 3D Newton solver

Parameters:

  • problem – to solve

Returns:

0 iff successful.

void fc3d_onecontact_nonsmooth_Newton_solvers_free(FrictionContactProblem *problem, FrictionContactProblem *localproblem, SolverOptions *localsolver_options)#

free memory for friction contact 3D Newton solver

Parameters:

  • problem – the global problem to solve

void fc3d_onecontact_nonsmooth_Newton_AC_update(int number, FrictionContactProblem *problem, FrictionContactProblem *localproblem, double *reaction, SolverOptions *options)#

Update friction-contact 3D problem: formalize local problem for one contact.

the rest is used to formalize the local problem)

Parameters:

  • problem – the global problem to solve

  • localproblem – the local problem to solve

  • number – (position in global matrix) of the considered contact

  • reaction – global reaction (only the block corresponding to the current contact will be modified

  • options – of the solver
