Detailed Description

template<class T>
class model::QuasiStaticModel< T >

A class for finite difference approximation of Peridynamics

We consider explicit schemes such as central difference and velocity verlet for time integration.

This class acts as a holder of lower rank classes, such as Mesh, Loading, InitialCondition, Fracture, etc, and uses the methods and data of the lower rank classes to perform calculation.

Note

1. We can run finite difference on any finite element mesh as long as the mesh consists of only one type of elements. We can mesh the domain using Gmsh and use its **.msh** file to run the finite difference approximation.

2. Currently only dimension 2 is supported.

3. Either triangle or quadrangle elements are supported.
