This widget is a table to set a geometrical 3D periodicity. It is a complex component but behaves the same way as many SYRTHES tables. The mesh has to be generated so that two periodic faces have the same topology.

The three first column correspond to the coordinates of an invariant point (Px,Py,Pz) in m.

the three following columns correspond to the definition of the axis of rotation (Ax,Ay,Az) for example (0,0,1) for a rotation around Oz.

The angle of rotation teta (given here in Degres).

the two following columns are used to set the groups of references (list of integer) identifying the references of periodic faces. Of course, integers specified cannot belong to both groups.

Becarefull when generating the mesh. Faces with references "Face group 1" must give faces with reference "Face group 2" when applying this transformation. The "-1" pseudo reference cannot be used for this table.

"User comments" allows to put a short description of the boundary conditions set.
