LKEY
Load key associated with surface load (defaults to 1). Load keys (1,2,3, etc.) are listed under "Surface Loads" in the input data table for each element type in the ANSYS Elements Reference. LKEY is ignored if the area is the face of a volume region meshed with volume elements.
你必须指出到底是什么单元类型。对于各个单元类型,Load keys 有不同的涵义。例如:
对于单元shell63,
Surface Loads Pressures -- face 1 (I-J-K-L) (bottom, in +Z direction), face 2 (I-J-K-L) (top, in -Z direction), | face 3 (J-I), face 4 (K-J), face 5 (L-K), face 6 (I-L) |
于是说,如果你的模型采用单元shell63,
lkey=1,对应 face 1 (I-J-K-L) (bottom, in +Z direction),表示压力作用在单元的面1上,
lkey=2,face 2 (I-J-K-L) (top, in -Z direction), 压力作用在单元的面2上,
够清楚了吧 |
