This utility is available for Polymer components. This feature is available for Plate Meshing, Co-extrusion and Melt Flow wizards. Improve mesh can be done only when tetmesh is successful. Click ImproveMesh, and a window showing the quality information of all meshed components except Land and Profile is displayed.

After clicking Yes, it performs a tetra remesh by maintaining the connectivity at the edges. After completion of tet remesh, you can verify the quality of the mesh by going to Model Summary.
