Hello,nThe geometry seems simple enough to have a structured mesh (I might be mistaken here but I'm going with the screenshots posted here). You might want to decompose your geometry such that you have a sweepable part. You should be able to use Multizone or Sweep mesh to generate a good structured mesh for this domain.nRegarding the high quality in the solid portion of the pipe, it is because the thickness of the pipe is so small compared to the length. This is the reason for the poor quality. Please see if you are able to create a structured mesh. The advantage is that you can have stretched meshes in the streamwise direction (length of the pipe).nKarthikn
