Hi,

Thanks for taking the time to read my post, I'd really appriciate any help which can be offered. I have several surfaces which are boundaries to my CFD domain that look like the attached image. I intend to extrude these surfaces outwards normal to the surface. As you can see there are some irregular cells on the surface and when extruded the shape of the channel becomes deformed. I have tried maually moving nodes to conform with the curve geometry but this only solves the problem ocassionally. Is there any setting/mesh repair process which can solve this and make the surface mesh flat, conforming to the surface curve geometry?

Thanks for your time and help.

I would suggest you to decrease the element size in general as you can see from picture 2 your geometry is not represented very well. The green surface is leaking out of the surface mesh in several places. Further you can define node spacing on the boundary curves (+refinement).
