Before you begin, generate a mesh on the source
geometry using any of the HyperMesh meshing algorithms, for
example 2D mesh with BL.

From the menu bar, click .
The Periodic Mesh dialog opens.

Select surfaces.

Use the Source: Surfaces selector to select source geometry.

Use the Target: Surfaces selector to select target geometry.

Use the Symmetry options to describe the mesh transformation between source and
target geometry.
Note: The Translation and Rotation options can be used simultaneously for one
transformation.
 To define the translation vector, select the
Translation checkbox.
 To define the rotation by an arc, defined by three nodes, or by an axis
and a rotation angle, select the Rotation
checkbox.

Check mesh and geometry.
 To whether source and target geometry are rotational and/or
translational symmetric or not, click Check/Modify
Geometry.
 To check for source and target mesh to determine if symmetry exists,
click Check Mesh.

Click Map Mesh.
The mesh from the source geometryis mapped onto the target geometry.
After a successful mapping step, information about the transformation is plotted in
the log region of the dialog.
