 ====== Backward extrusion ======
-  * A tool cuts and divides a piece of metal into two parts
+  * A cylindrical piece of metal is pushed through a rigid tool.
-  * A guess of the final stationary shape of the chip is used as initial mesh.
+  * A very thin mesh is placed where the solid is supposed to go out.
-  * The final shape (chip width) is automatically computed  by the ALE method
+  * During the process, this flat mesh grows due to the convection and the main mesh shrinks.
-  * The mesh is refined near the crack.
+  * The shape of the mesh remains good and no remeshing is needed.
-  * The model could be highly improved with an appropriate cracking model.
