extraire_surface_ale

Defined in: src/Fluid_Structure_Interaction/ALE/Extraire_surface_ALE.cpp

Extraire_surface_ALE in order to extract a surface on a mobile boundary (with ALE desciption).

Keyword to specify that the extract surface is done on a mobile domain. The surface mesh is defined by one or two conditions. The first condition is about elements with Condition_elements. For example: Condition_elements x*x+y*y+z*z<1

Will define a surface mesh with external faces of the mesh elements inside the sphere of radius 1 located at (0,0,0). The second condition Condition_faces is useful to give a restriction.
