Hi guys, i have a problem of mesh quality. When i check the mesh in Fluent, there is an error of 'negative cell volume'. Does someone can make a good mesh taking attention to make it more dense inside the crevice?

Thank you in advance

As ANSYS employee, we can not download attachments. 

Can you please insert images describing your problem?

If you are working with workbench meshing, please see following video. 

If you have case file then do following. 

read case in fluent

define/beta y y to enable beta feature

q to exit from define

switch to meshing mode

mesh - tools - auto node move

quality measure - inverse ortho skew


again switch to solution.

This is just 2d sketch

Is this revolved around any axis or is this cross section.
