My Triangulation part is followed and the pictures of the initial and distorted mesh is attached. I appreciate it if you could guide me to the reason behind this problem.

I don't think it's the generation of the mesh, but that it has to do with either (i) computing the displacement field, or (ii) how the displacement field is used in deforming the mesh.

Since you have hanging nodes, do you apply hanging node constraints to the displacement field you then put into MappingQEulerian? And how do you generate the plot with DataOut?
