mat，r，mp，et都什么意思啊 ？
mat，r，mp，et都什么意思啊 ？建模的时候用到不止一种材料，定义起来不知所然了
一直显示 No results sets on the results file.
还有一直显示Real constant 1 referenced by at least element types 1 and 2.
下面是我定义的
!********
et,1,shell181
R,1,hs
R,2,hm
mp,ex,1,2e5
mp,prxy,1,0.3
mp,ex,2,820
mp,prxy,2,0.9
sectype,1,shell,,
secdata, hs,1,0,3
secdata, hm,2,0,3
secdata, hs,1,0,3
KEYOPT,1,1,0
KEYOPT,1,3,0
KEYOPT,1,8,2
KEYOPT,1,9,0
KEYOPT,1,10,0
!********
mp,ex,3,2e10
mp,prxy,3,0.3
sectype,2,shell,,
secdata, hs,3,0,3
secdata, hm,3,0,3
secdata, hs,3,0,3
!********
et,3,shell181
R,5,Belly_b
R,6,Panel_b
sectype,3,shell,,
mp,ex,4,2e5
mp,prxy,4,1.3
大家看有定义重复或者重叠的么 MAT, MAT
Sets the element material attribute pointer.
R, NSET, R1, R2, R3, R4, R5, R6
Defines the element real constants.
MP, Lab, MAT, C0, C1, C2, C3, C4
Defines a linear material property as a constant or a function of temperature.
ET, ITYPE, Ename, KOP1, KOP2, KOP3, KOP4, KOP5, KOP6, INOPR
Defines a local element type from the element library.
