pipe elbow stress modelling
pipe elbow stress modelling
(OP)
I am trying to develop a model for an elbow in thick-walled power piping where the wall thickness is non-semitrical due to errosion / corrosion. This model is not one of the standard models in ANSYS or Abaqus which are the two FEA programs that are available to me. Thanks for your help.

answer: do it with splines/ curves, but it will be somewhat difficult.
if you have autocad (or similar free program), you can cut the pipe, photograph its profile, insert into drawing and draw the shape based on it.
then you can import it into abaqus somehow (dxf, dwg) or make a 3d model in autocad.

ANSYS has the advantage of being able to use a local toroidal coordinate system built-in. ABAQUS has no such thing. If I had the choice, I know which program I would use...
