Definition of a structure to handle friction-contact (2D or 3D) problems.

Functions

FrictionContactProblem *frictionContactProblem_new(void)
FrictionContactProblem *frictionContactProblem_new_with_data(int dim, size_t nc, NumericsMatrix *M, double *q, double *mu)

new FrictionContactProblem from minimal set of data

Parameters:
