Go to the source code of this file

Typedef and functions declarations related to NCP-Fixed Point 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

Functions
