Ansys APDL cylindrical surface

Ansys APDL cylindrical surface

(OP)
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...

CODE --> APDL

! 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,

eBook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook – How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final product’s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
