Icem is a efficient meshing editor for fluid and solid mechanic. It generates 2D and 3D mesh, structured or unstructured with hexaedral, prism or tetraedral elements. In this study, the aim is to use icem prism mesher.

Icem is divided into three parts :
 
        - DDN which allows to define geometry (points, lines, surfaces).
        - DDN-> Tetin in order to define families of lines or surfaces which will correspond to boundaries conditions.
        - Meshing : Hexa, Tetra, Prism.
