  Hello, I am working on a fatigue crack growth analysis and have a problem when i try to use a smart crack growth option. Method: SMART keeps turning red. I have done the same simulation on the same object in 3D analysis and it worked fine, but when i switch to 2D this problem occurs.
  Is there some setting or condition that should be set for it to work?
  For pre-meshed crack i used nodal named selection (vertex) as shown in the picture below.
  Here is also a picture of a mesh I made around the crack. I used a sphere of influence.

  Hello ezy,
  Smart crack growth tool in workbench supports 3D analysis only, to know more about it’s assumptions and limitations, go through this link below.

  For modelling this in 2D, check this Ansys help document on Fracture mechanics:
  Chapter 1: Understanding Fracture Mechanics (ansys.com)
  1.2. Understanding How Fracture-Mechanics Problems Are Solved (ansys.com)
