The translator creates a grid and boundary conditions file in the Cedre file format.
The face marking is supported on boundary faces or internal faces. In the Cedre Boundary Condition menu, a "face family" must first be selected. Note that a face family is defined as a family composed solely of 2D elements for a 3D mesh, or a family composed solely of 1D elements for a 2D mesh. Then the boundary conditions "Boundary Mark" can be added to this family. The default name (mark) is set to the family name. This can be changed to any character string.
The translator supports 3 types of meshes. In Cedre, these are
refered to with the names 2D_AXI, 2D_PLAN
and 3D. For a mesh type 2D_PLAN,
the translator computes automatically the normal to the plane. For
a mesh type 2D_AXI, the translator needs to inquire information
about the axis of symmetry. The user must define the axis of symmetry
using the option "Mesh parameters: 2D Axisymmetry parameters".
When selecting this option, the user is prompted to enter the coordinates
(x, y, z) of a point on the axis of symmetry, as well as a vector (UX,
UY, UZ) along this axis. Note that the axisymmetry parameters can
only be defined on a surface family (2D elements) and should be defined
The periodicity is supported on boundary faces only. The periodicity
must have been first defined in the mesh generator. In addition,
the periodic face families must be tagged as such in the boundary conditions
file. In order to do so, a "face family" must first be selected,
then the boundary condition "Periodic Face" must be selected. This
should be done for each family that are part of the periodicity.
