Here *type* sets the number of integration points in an element.
It should be set to **-normal**, **-minimal** or to **-maximal**.

For **-tria3** elements and **-tet4** elements, the integration
point will be located in the middle with **-minimal** integration,
or the integration points are located in the nodes with **-maximal** integration.

For **-tria6** elements and **-tet10** elements, the integration
point will be located in the in the nodes,
irrespective of this **group_integration_points** record.

For other elements, if **-minimal** is used then
the number of integration points in a direction is set equal to
the number of nodes in the direction minus 1, and gauss integration is used.
If for the other elements **-maximal** is used then
the number of integration points in a direction is set equal to
the number of nodes in the direction, and lobatto integration is used.

Default **-minimal** is used for **-bar2**, **-tria3** and **-tet4** elements;
it is default **-maximal** otherwise.

If *type* is set to **-normal**, the default integration will be used.

For third or higher order elements (**-bar4**, **-quad16**, etc.)
you always need to use **-minimal** if **materi_velocity** is initialized.

The *index* specifies the element_group, see **element_group**.
