*SYMMETRIC MODEL GENERATION
2. Angular scaling factor in the circumferential direction with respect to the original sector. The
default is 1.0.
Repeat the third data line as often as necessary to define all the sectors of the model in the circumferential
direction.
Subsequent lines (needed if the surface meshes on either side of the original sector are not matched
completely):
1. The surface name on one side of the original sector.
2. The corresponding surface name on the other side of the original sector, measured at a positive
angle, , around the revolving axis.
3. Tolerance distance within which nodes on one surface of a sector must lie from the
corresponding surface of the neighboring sector to be constrained. Nodes on the surface of
the sector that are further away from the corresponding surface of the neighboring sector than
this distance are not constrained. The default value for this tolerance distance is 5% of the
typical element size in the surfaces of the original sector.
4. Include the “word” SURFACE (default) to generate a surface-to-surface type of constraint or
the “word” NODE to generate a node-to-surface type of constraint.
Repeat the subsequent data line as often as necessary to define more pairs of corresponding surfaces
on each side of the original sector. Constraints between the neighboring pairs of corresponding surfaces
will be applied with the automatically generated *TIE option when the periodic three-dimensional model
is generated.
