- Go to Utilities and open Preferences window. In the Meshing - General branch there is the option Size transitions. This option defines the transition gradient of element sizes (size gradient), whose values are between 0 and 1. The greater the size gradient is, the sharper change of sizes in space. To test this, enter the value 0.4 and click Accept Apply.
- Again, generate the mesh (Mesh->Generate mesh) with the same general mesh size.
Mesh with the elements concentrated around a point, with a size gradient of 0.4.
- The size gradient (0.4) results in a higher density around the point (see figure).
- Now go back and enter 0.6 in Size transitions. This will result in a mesh more suitable for our objectives. Click Accept Apply.
