Description oft he data types

The basis for all data is the finite element mesh (triangles and quadrilaterals). Through this mesh, which consists of nodes and elements, the geometry and geographical features of interest are reproduced. Each element and each node must be numbered. These numbers are used to assign the individual data. The geometric data is referred to as an identifier with the other types of data referred to as attributes. The data types can be divided into four broad groups

• Geometric data

• Material data

• Boundary condition and source terms

• Auxiliary data for further analysis and visualisation

In the following descriptions:

1K: only for models with 1D fractures

2K: only for models with 2D fractures

If no model type is specified, the appropriate data type is useful for several types of models.
