Hi everyone,

I have been trying to mesh with ANSYS a microcanal geometry you can see below for one week. I've basically meshed the whole domain as one part with triangles and included a boundary layer where the section of the 2D-tube is constant. However after having check the mesh with Fluent the software displays me a warning message that begins as :

WARNING: The mesh contains high aspect ratio quadrilateral, hexahedral, or polyhedral cells. [...]

After a mesh quality checking, I saw that the grid was not so good. I think I've found the region that is problematic. It seems to be the one where the diameter of the tube changes ; the connection between the boundary layer and the global triangular pattern generates some strange geometries.

I have no idea how to resolve that. Can anyone help me please ?
