WebMesh coarsening Mesh coarsening removes existing mesh vertices therefore reduces the size of the mesh. It is useful in the adaptive mesh generation. TetGen provides two options for coarsening tetrahedral meshes: The user can select vertices to ratain or remove in the coarse mesh. TetGen will remove those vertices which are removable. WebAny field values above the upperRefineLevel will trigger mesh coarsening. 2.4 UnRefine Level unrefineLevel 0.0005; When the value of the desired quantity in a cell falls below this value, the cell will be coarsened.
