Notes
- For element types and surface numbers, refer to "Chapter 4 Element Library".
- A surface is defined by a combination of an element and a local surface number. Any number of surfaces may be entered on one line. Any number of lines may also be inserted until the next option begins. Each (element, local surface number) pair must be on the same line.
- Elements to be specified must be defined before "
!SGROUP". - If an element is not defined by the "
!ELEMENT" option, it is ignored and a warning message is displayed. - A surface containing an element not defined by the "
!ELEMENT" option is excluded and a warning message is displayed. - A surface whose element type and surface number are inconsistent is excluded and a warning message is displayed.
- A single group may be defined in multiple separate definitions.
Example
!SGROUP, SGRP= SUF01
101, 1, 102, 1, 103, 2, 104, 2
201, 1, 202, 1
501, 1
!SGROUP, SGRP= SUF02
101, 2, 102, 2
!SGROUP, SGRP= EA01 --- "(601,1), (602,2)" are added to group "SUF01".
601, 1
602, 2
Incorrect Examples
Example 1 [An (element, local surface number) pair spans multiple lines]
Example 2 [The local surface number is inconsistent with the element type]
