How to refine a mesh in a 3D cylinder
Hello
How to refine my volume mesh into a cylinder ? |
Can you give bit more detail as to what you are trying to do?
Thanks, Sarang |
I have a pipe with a valve, and I would like to refine my mesh at the entrance and exit of the pipe and valve to gain more precision and computation time.
|
before meshing the hole pipe and valve (Volume meshing), first u place more no of grid point on the edges near the entrance and exit and then mesh the volume.
|
If you are trying to refine the volume, you need to create a density box... This is one of the options under the mesh tab. If you create a density region from 2 points, it will create a cylinder. The radius of the cylinder is the mesh size you set times the width (number of elements of that size)...
Basically, a density box or density region is a way to locally control the max size in a volumetric region defined by points or entities. It only works with tetrahedral meshes and surface meshes created from them (such as patch independent octree surface mesh). |
oops, sorry, you were asking about gambit. Ignore the last response, it was for ICEM CFD.

if we take only one cylinder, how to refine the mesh at the entrance? For your information, I create the cylinder and I draw a line between two points located on the faces of the input and output, then I refine my line and mesh them after i mesh my volume, but it doesn't work. |

hopefully it will help u.plz see section Specifying the Grading Scheme

Thank you, I found the solution.
Just refine the surface mesh of the pipe and also to refine the mesh of a plane that intersects the cylinder 2 and the end must be the volume mesh. |
use size functions...

Thank you for your answers, they were very helpful to me.
Banty thank you, your answer was the solution for me. |
