SubscriberI'm trying to determine the energy release rate at the crack tip of an adhesive. a simple 2D model has been created and a pre-mesh crack was created also. The following warning always appears after solving the problem.
"The fracture parameters computed during solution may be incorrect. Check the Solver Output on the Solution Information object for possible causes".
When I check the Solver output I see the following points:
1- Fracture parameter calculation issue: crack tip node is attached to an element type that is not supported, Crack 1, crack tip node 15, element type 169. The element will be ignored.
2- Fracture parameter calculation issue: Contour integration for crack 1 includes contact elements that are not supported. These elements are ignored, and the contour integration results may not be correctly calculated.
Could you please help me to find a solution to remove this warning?

Ansys EmployeeHi,
For the warning message, in the contact scoping you should remove the surface segments connecting the tip node from the definition.
