!DLOAD

Definition of distributed load

Parameter

GRPID = Group ID
AMP = Time Function Name (Specified in !AMPLITUDE, valid in dynamic analysis)
FOLLOW = YES(Default) / NO
(whether pressure load follow deformation, valid in finite displacement analysis)

** 2nd Line or later **

(2nd line) ID_NAME, LOAD_type, param1, param2,...
Parameter Name Attributions Contents
ID_NAME I/C Surface group name, element group name, or element ID
LOAD_type C Load type No.
param* R Load parameter (refer to following)
