Hello! I am struggling with improving the mesh above the pipe as shown in this diagram. What can I do to fix it? The pipe's curved surface in this diagram is in contact with the absorber plate and it is a rectangular surface.

What changes can I make for improvement?

The pipe is surrounded by PCM, and in this diagram, the mesh is all curved in the PCM area as well. Is it alright to leave it like that or should I do some improvement?

Hello,

How did you block the internal cylinder, have you used an O-Grid? O-Grids can drastically improve element quality around circular objects.

It would help to add an image of your blocking.
