本帖最后由 wrj001 于 2021-9-8 14:38 编辑当要设定的表面为实体单元表面时，可用S1,S2,......,S6 指定要定义的表面。
如：
*ELSET, ELSET=EUP
6385, 6386, 6387, 6388, 6389, 6390, 6391, 6392,
6393, 6394, 6395, 6396, 6397, 6398, 6399, 6400
*SURFACE,TYPE=ELEMENT, NAME=SUP
EUP,S2
*SOLID SECTION, ELSET=POLE, MATERIAL=STEEL
*MATERIAL, NAME=STEEL
*ELASTIC
21000,.3
*BOUNDARY
LOW,1,3
*STEP
*STATIC
*DSLOAD
SUP,P,-10.
*END STEP
