The elementType definition has to be of the following form:

**Elements**

One of the following element types needs to be included in the definition (``elementType[0:5]``).

- **Quad4**    - quadrilateral 2D element with 4 nodes.
- **Quad8**    - quadrilateral 2D element with 8 nodes.
- **Hexa8**    - hexahedron 3D element with 8 nodes.

**additional Parameters**

The following optional Parameters are also included in the element type definition.

- **R**     - reduced integration for element, in ``elementType[5]``, currently possible for Q8 and Q4.
- **E**     - extended integration for element, in ``elementType[5]``, currently possible for Q4.
- **PE**    - use plane strain for 2D elements, in ``elementType[6:8]`` or ``elementType[5:7]``.
- **PS**    - use plane stress for 2D elements, in ``elementType[6:8]`` or ``elementType[5:7]``.

.. note::
    If R or E is not given by the user, we assume regular integration.

    If PE or PS is not given by the user, we assume PE.

Example of the usage of a quadrilateral element with 4 nodes, regular integration and plane strain.
