For every face, the original cell in mesh. More... | |
A surface formed by the iso value. After "Regularised Marching Tetrahedra: improved iso-surface extraction", G.M. Treece, R.W. Prager and A.H. Gee.
The handling on coupled patches is a bit complex. All fields (values and coordinates) get rewritten so
Now the triangle generation on non-separated processor patch faces can use the neighbouring value. Any separated processor face or cyclic face gets handled just like any boundary face.
