Ansys APDL cylindrical surface 1

[WillBerg]

Hi,

how can a cylindrical surface be programmed in Ansys APDL, in cylindrical coordinates? I try to assamble one with a,,,, command,from sectors, but no matter in how many sectors I divide it(2, 3, ...80) it throws an error "circle trying to span greater than 180 degrees" and fails to generate one of the areas.

Thanks!

Hi McWhite3,

See if either of this works for you...

! Using ADRAG
/prep7
r = 0.1
L = 0.3
csys, 1 
k, 1, r, 0
k, 2, r, 120
k, 3, r, 240
l, 1, 2
l, 2, 3
l, 3, 1

k, 4, r, 0, L
l, 1, 4 ! path
adrag, 1, 2, 3,,,, 4

! Alternately using A...
! But first delete existing lines and areas
alls
adele, all
ldele, all
a, 1, 2, 6, 5
a, 2, 6, 7, 3
a, 3, 7, 5, 1

Kind regards,
Jason

Here's another way:

csys,1
cyl4,0,0,0,0,1,360,12
vdele,all
asel,s,loc,z,0
asel,a,loc,z,12
adele,all
allsel
aplo
