Detailed Description

class gsurf

this class defines general surface, which can be used in connection with general finite elements only topological informations are collected

the class is motivated by solution of hemivariational inequalities, in 3D problems, there is a contact between two parts of a body matching mesh is assumed and therefore two elements share
