Optimizing Meshes

Optimize redistributes and reshapes the triangles within a mesh, to obtain a more homogeneous mesh.Be aware that this optimization tends to modify the shape of the model.

  1. Select a manifold mesh.

    The sphere represents the Maximum Length.

    Minimum Length and Maximum Length refer to the length of the edges of the triangles.

  2. Set the Minimum Length, Maximum Length and Dihedral Angle according to your needs. Choose values coherent with your model.

    Optimize is an iterative operator using edge splits and edge collapses:

    • If an edge is too long, it is split in two (Maximum Length).
    • If an edge is too short it is collapsed (Minimum Length).
    • Minimum Length must be less than or equal to the half of Maximum Length.
    • The Dihedral Angle between 2 triangles sharing an edge is the angle between their normal.

  3. Select the Analysis check box to display the maximum and the mean deviations.
