3.5 Material Section

The material section is defined by the Material element. This section defines all the materials and material parameters that are used in the model. A material is defined by the material child element. This element has two attributes: id, which specifies a number that is used to reference the material, and type, which specifies the type of the material. The material element can also have a third optional attribute called name, which can be used to identify the material by a text description. A material definition might look like this:

<material id="1" type="neo-Hookean">

Or, if the optional name attribute is present:

<material id="2" type="rigid body" name="femur">

The material parameters that have to be entered depend on the material type. A complete list of available materials and their parameters is provided in Chapter Materials.
