Hi .
I have a problem with the mesh that I present below. is a 2D pipe that consists of two domains, one domain for the fluid and another small solid domain that represents the skin of the pipe. For reasons of my model and my research work I build the structured mesh in the solid zone and triangular mesh in the fluid zone. The problem is that I can not avoid generating elements of poor quality in the corners between the fluid and solid domains. Someone who could help me with this problem, I would greatly appreciate it. I work the mesh with Ansys Meshing.

I attach an image.
