28 CHAPTER 3. COMMAND DESCRIPTION
3.4 *EL REMOVE: Removing the element from the model
The *EL REMOVE is used to remove the elements from the model based on a given criterion.
The command is specially for the application of the local approach based fracture mechanics
analysis.
The following parameters are required:
VARIABLE Set this parameter equal to identifier of the variables which
is used as the criterion for removing elements. If a variable
in any integration point of an element satisfies the given
criterion, this element is removed and it will not appear in,
for examples, the deformed mesh plot and the contour plot.
GT Set this parameter equal to a critical value of the VARI-
ABLE for removing the element, if the defined variable is
greater than this values, the element will be removed.
The following parameter is optional:
ELSET Set this parameter equal to element set name in which the
elements may be removed. The default is the whole model.
Examples:
1. Use the following entry to conduct element remove in the element set E0000001. If the vari-
able SDV2 in any gauss point of an element is greater than 0.10, this element will be removed.
*EL REMOVE, VARIABLE=SDV2, GT=0.10, ELSET=E0000001
2. Use the following entry to conduct element removing in the whole model.
*EL REMOVE, VARIABLE=SDV2, GT=0.10
