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.

SMART Crack-Growth Assumptions and Limitations (ansys.com)

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)
