I am putting a crack of 5mm in a rectangular model and using XFEM module to define the crack. I am getting this warning continuoulsy.

Please help me how to avoid this or what can be the reason of this warning

Try extending the initial crack geometry a bit beyond the model. You may also have to adjust the mesh a bit so that it's not perfectly aligned with the initial crack - sometimes it might be necessary to use an unstructured mesh.
