I have to model a semi-elliptical crack with singular meshing in 3D.
I am able to create half model. But I want a full model with the crack (as my loading is antisymmetric). Hence, I use the reflect command and reflect the volumes with mesh.
After reflecting, I am trying to merge the common nodes in the crack plane, leaving the nodes from the crack region, so as to get a crack.
While merging, I get error- data corrupted, Negative jacobian matrix error. When I plot the error elements, I see the singular elements along the crack front.
Experts I am a novice and not sure if this is the correct procedure.
