Is it possible to use XFEM in ANSYS without an initial crack?
Is it possible to define a crack tip without using XFDATA? that mean using nodes or a component of nodes (not elements)
I feel that XFEM model of ABAQUS is more accurate and widely used tool. Yes it is possible in ABAQUS to use XFEM model without defining initial crack in which case the model predicts the crack initiation sites considering the applied boundary conditions.
Please refer to the following publication in which we developed such model, I hope it will be very helpful.

Unfortunately there is no such feature (XFEM) in ANSYS but there is in ABAQUS
I agreed with Dear Basim Fadhil, ANSYS Soft doesn't contain such feature.
