The tutorial projects demonstrate the functioning of the different modules of the NeoPZ library

How to create and use integration rules

NeoPZ includes integration rules of arbitrary order for all element topologies. This program illustrates how to create an integration rule for a given topology and validates the rule for a simple integral

This tutorial also verifies if the objects are able to integrate a polynom of order 500 and prints the number of necessary points

It is nice introduction in the use c++ classes

To create geometric mesh

The tutorial discShape implements a bi-dimensional problem using as mesh a disc with a central hole.

It initializes given the coordinates of the 10 points on the circunference and another 10 points on the , where is the radio of the hole. Then it constructs a quadrilateral elements jointing two next nodes on external boundary with another two nodes on internal boundary (hole). Also creates 20 boundary (one-dimensional) elements on external and internal boundary.

After creating the geometrical mesh with nodes and elements, it is necessary to construct the connectivity between them calling BuildConnectivity().
