Using mesh Density
 

Hello to all,

I'm trying to generate a mesh for a 3D geometry. I have successfully created a Tetra/Mixed mesh using Octree method. Now I want to create a mesh density box to refine the mesh near the bifurcation.

I have created 8 points in the region of interest. (Image 1)
After that I have created the density box. (Image 2)

Size information:

Maximum size: 0.0006
Min Size limit: 0.0004

Density box size: 0.00025

Now as you can see, mesh has been refined at the bifurcation region(image 3). However, it is somehow altered the mesh size in the smaller branch (Image 4).

Am I doing something wrong?
Any help would be appreciated.

Best wishes
