一个模型，定义了梁、板单元，并用鼠标选定全部几何单元后施加SELFWEIGHT以及其他荷载。分析后出现WARNING：
APPLIED SELFWEIGHT IS LESS THAN TOTAL WEIGHT OF ALL STRUCTURE ELEMENTS IN LOAD CASE 5 ALONG Y.
THIS COULD DUE TO BE SELFWEIGHT APPLIED TU SPCIFIC LIST OF MEMBERS/PLATES/SOLIDS/SURFACES.
TOTAL UNFACTORED WEIGHT OF THE STRUCTURE=2983.196KN
TOTAL UNFACTORED WEIGHT OF THE STRUCTURE APPLIED=2342.595KN

有人能帮解释下为什么吗？APPLIED WEIGHT跟实际模型单元的SELFWEIGHT不是一回事吗？我就想给模型施加自重荷载，应该怎么样保证全部加上啊？是不是在定义selfweight的时候施加一个系数（对于本例，系数就是2983.196/2342.595=1.273）？

用Assign to View指定荷载试试。

定义SELFWEIGHT时系数为1或者-1，然后指定全视图。
