perry你好，谢谢你的提供。我另有一关于压电矩阵的输入问题请教。
三维压电矩阵的输入方法是：
MP,DENS,4,7700 ! Density of piezoceramic (kg/m**3)
MP,PERX,4,6.45E-9 ! Permittivity of piezoceramic (F/m)
MP,PERY,4,5.62E-9
MP,PERZ,4,6.45E-9 ! used in 3-D analysis
           ! 3-D Analysis
TB,PIEZ,4 ! Piezoelectric "e" matrix of piezoceramic TBDATA,2,-5.2 ! e31 ! (C/m^2)
TBDATA,5,15.1 ! e33
TBDATA,8,-5.2 !e31
TBDATA,10,12.7 ! e15
TBDATA,15,12.7 ! e15
!
TB,ANEL,4 ! Stiffness "c" matrix of piezoceramic
TBDATA,1,13.9E10,7.78E10,7.43E10 ! (N/m^2)

TBDATA,12,11.5E10
TBDATA,16,2.56E10
TBDATA,19,2.56E10
TBDATA,21,3.06E10
按照帮助文件的说法，将C矩阵变为4X4阵，E阵变为4X2阵即为二维压电矩阵，但我一直高不清 TBDATA，？，value中取值的初始序号怎样填写。请看我下面的输入对否？
TB,PIEZ,4 ! Piezoelectric "e" matrix of piezoceramic 2-D Analysis
TBDATA,2,-5.2,0,0,15.1 ! e12,e22 ! (C/m^2)
