NOEUD I 1 X 0 Y 0 I 1 X 1 R 10 I 20 Y 1 Q 5. This command is useful particularly for refining part of the mesh and for connecting a geometric model to an existing mesh. The commands which use the concept of line (for example, the automatic mesh generator) do not create new nodes on these lines.
The program preserves the connection between the nodes and the lines. BORD command enables nodes to be attached to lines. LISSAGE RECOMBINE ! Recombination of triangles into quadrangles RELOCALISE ! Relocation of the nodes to enhance the quality of the mesh VI GEN MODIFIE LIGNE 1 2 DOMAINE 2 ELEMENT 4 ! Elements are imposed on the 2 arcs of the circle MAILLAGE OFFSET ! Generating mesh GENERE !

Let us mesh a support embedded on a wall with imposed passing points. DES FIX CHAR VI ! Display of boundary conditions PHP ATTR 1 THICKNESS VAL 2.E-3 !

This example consists in meshing a console beam defined in the Z=0 plane, by using the offset mesher.
