Hi all,
I am trying to perform a 2D beam analysis where I want to incorporate cracks using interface elements. My approach is to model the cracks explicitly as interface elements. However, I am running into an issue: since the interface element is defined as a 2-point surface, I am unable to assign a structured mesh along the beam. When I try, I get the following error:
“No valid surfaces selected (only 4-sided or 3-sided or NURBS are valid).”
Has anyone faced a similar problem or have suggestions on how to properly mesh a 2D beam with interface elements representing cracks? Are there any recommended workarounds for this limitation?
Thanks in advance for your help!
