SMART crack problem

Polymer93

Hi everybody,

i have a question. I was doing a bending test and was hoping to apply SMART crack onto the simulation in order to see if the applied strain will lead to crack propagation within the material. I was following a tutorial for the characterization of the pre meshed crack which has worked for me in the past.

However, a questionmark is still behind the SMART crack tab. Does anybody have an idea as to what could be the problem? I have included a few screenshots.

I would be grateful for any advice or comment!!

Does your mesh contain hex elements? SMART only works with tet meshes.

Thanks for the reply. No the mesh only contains a tet mesh. I might have found the problem. I think it was the contact behavior applied to the model. SMART only allows for bonded contact.
