Hi all,
I have a strange problem with Salome. My structure is a cylinder. In order to mesh it, i have to devide it into 5 parts, 1 box at center and four hexahedrons around. Then i made a compound of these 5 parts. By that way, i can mesh by using hexahedron elements. But after deformation, these 5 parts seem to be not connected each other. I do not understand why? Could anyone help me to explain? What should I do if I want to mesh for a cylinder by hexahedron elements?
Many thanks in advance.

When you create a Compound object, Salome does not merge the touching faces and when you mesh the volumes, yoou will not get a joined mesh.
To cicumvent the problem there are two ways:
1) in GEOM use the boolean union tool to merge your volumes and then use the partition tool to split this single volume in separate parts (partition tool will create \"common\" surfaces between adjacent volumes => continuous mesh)
2) in MESH: merge the coincident nodes with the \"Merge nodes\" tool (especially efficient with mapped meshes..)

Hi
I have another question. In Post Processing, how can i present the stress on the deformed shape? Thank you.
