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.
