*EULERIAN SECTION

Specify element properties for Eulerian elements.

This option is used to define properties of Eulerian continuum elements, including the list of materials that may occupy the elements.

Required parameters

ELSET

Set this parameter equal to the name of the element set containing the Eulerian elements.

Optional parameters

ADVECTION

Set ADVECTION=SECOND ORDER (default) to use a second-order algorithm to remap solution variables after remeshing has been performed.

Set ADVECTION=FIRST ORDER to use a first-order algorithm to remap solution variables after remeshing has been performed.

CONTROLS

Set this parameter equal to the name of a section controls definition (see Section Controls) to be used to specify a nondefault hourglass control formulation option or scale factor. The SECTION CONTROLS option can be used to select the hourglass control and order of accuracy of the formulation.

FLUX LIMIT RATIO

Set this parameter equal to the ratio between the maximum distance a node is allowed to move during one increment and the characteristic length of the Eulerian element containing the node. The value of this parameter must be positive. The default value is 1.0, and the suggested range for the value is between 0.1 and 1.0.

Data lines to define Eulerian elements

First line

  1. Material name.

  2. Material instance name (optional). The default material instance name is the same as the material name. Material instance names must be unique throughout the entire model. Specify a nondefault material instance name if you refer to the same material definition more than once.

  3. Orientation name (optional). If not defined, the global coordinate system is used for the material. All orientation-dependent materials in the Eulerian section must be defined in the same local coordinate system.

Repeat this data line as often as necessary to define the list of all materials that may appear in the Eulerian section.
