• Only the interesting part of the problem is meshed, thanks to the ALE formalism.
• The mesh is Eulerian in the rolling direction and Lagrangian in the transverse direction.
• The stationary state is reached by first clamping the sheet between the rolls and secondly making them rotate around their axis.
• The rolls are rigid and the sheet is thick.
• The free surface of the sheet in the outlet zone is automatically computed using spline remeshing.
• Eulerian convection of the Gauss points values is performed using a 1st order Finite Volume algorithm.

The comparison between ALE (above) and Lagrangian (below) models is presented:
