3.16 Discrete Section¶

This section defines the materials used by the discrete elements and assigns these materials to the discrete elements sets defined in the Mesh section. The materials are defined via the _discrete_material element and the materials are assigned to discrete element sets using the discrete _element.

<Discrete>
  <discrete_material id="1" type="linear spring">
    <E>1.0</E>
  </discrete_material>
  <discrete_material id="2" type="linear spring">
    <E>2.0</E>
  </discrete_material>
  <discrete dmat="1" discrete_set="springs1"/>
  <discrete dmat="2" discrete_set="springs2">
</Discrete>

The _discrete_material and the discrete _elements are defined in more detail below.

Discrete Materials¶

The _discrete_material section defines a material that can be assigned to a discrete element set. The id attribute defines the material ID and the type _attribute defines the material type.

Discrete Section¶

After the discrete materials are defined, the materials are assigned to the discrete element sets that are defined in the Mesh section using the discrete element. This element requires two attributes:

attribute	Description
dmat	discrete material ID
discrete_set	discrete element set defined in the_ Mesh_ section.

Example:

<discrete dmat="1" discrete_set="set1"/>
