Note:
- For the element type and surface number, refer to "Chapter 4 Element Library".
- The surface consists of a combination of (elements and local surface numbers). Any number of surfaces can be inserted in one line. Any number of lines can be inserted until the next option starts. The combination of (elements and local surface numbers) must be in the same line.
- It is necessary to define the element to be specified before "
!SGROUP".- The element not defined in "
!ELEMENT" option will be excluded, and a warning message will be displayed.- The surface which includes the element not defined in "
!ELEMENT" option will be excluded, and a warning message will be displayed.- The surface where the element type and the surface number are not consistent will be excluded, and a warning message will be displayed.
- One group can be defined by dividing into multiple groups.
Example of Use
!SGROUP, SGRP= SUF01
101, 1, 102, 1, 103, 2, 104, 2
