Hello, I'm running a fairly simple Mode I fracture simulation on a beam with a special shape. I'm using the VCCT feature to "separate" the two halves of the beam. Everything works fine and the force convergence is good but when I go into the results I find this:
It's like if the nodes on the other edge weren't cracking. Honestly, I have no clue why this is happening, I´ve refined the mesh and the problem is still there. Since it's a Mode I fracture I only have Critical Mode I Energ Release Rate as a parameter I know for sure (from experimentation) ans it's very low, for Mode II and III I've used the same value but I was thinking of putting either a very big one or a very small one (0).
The boundary condition is a fixed support on one side and a small displacement on the (Y) axis. I haven't set the pre-meshed crack as symmetric. Let me know how can I fixe this. Also, the Crack Length growth in all the percentages is always 0 mm, I assume because of this non-cracking nodes but in the middle it' shouldn't be 0.
