Dear all,
Are there some tips when making FEA analysis of composite laminated structures using ANSYS Code .As far as I am concerned ,first I should define the element type (such as solid46,191) with real constants for orientations of each ply, then establish the local coordinate system assigning to Element coordinate System. After the meshing, I have to check the orientation of the element coordinate system(ecsys) especially for irregular structure such as a plate with a hole and modify the ecsys one by one. Actually it is an tedious work. Is there any artifice to make the program more efficient?
Thanks in advance.

It is not the point
I mean when assigning the cylindrical coordinate system (csys ) to the element csys before meshing , the x coordinates of the elemeng csys will be along the radial directions . If I want that along the circumferential directions , I have to create local csys for every elements as
elemeng csys. some APDL code as follow :
fini
/clea,start
/prep7
et,1,42
r=10
t=2
na=nint(acos(-1)*r/2/(2/3))
nb=3
ag=90/na
csys,1
k=0
*do,i,1,nb+1,1
*do,j,1,na+1,1
k=k+1
n,k,r+(i-1)*t/3,(j-1)*ag,
*enddo
*enddo
*do,i,1,nb,1
k=0
*do,j,1,na,1
k=k+1
local,10+k,0,,,,90+ag/2+(j-1)*ag
esys,10+k
e,j+(i-1)*(na+1),j+i*(na+1),j+1+i*(na+1),j+1+(i-1)*(na+1)
*enddo
*enddo
for some complex structures , this method is too tedious
