DEFINITION
ROTSYM specifies the conditions for a rotational symmetry condition. Rotational symmetry is a boundary condition in which symmetry is a special case. It is a matching of the velocity on one (master) surface of a body to another (slave) surface on the same body. As a special condition, rotational symmetry condition can be used to specify periodic symmetry condition on the master and slave surfaces. For periodic boundary condition (PBC), it is required to specify a master to slave direction vector with having the point set to (0, 0, 0). The angle is required to set 360 degrees.
REMARKS
It is recommended that if users use this, that the meshes on the two sides have identical topology. If not, a fine mesh is recommended. Applicable object types: Elastic, Plastic, Elastoplastic, Porous
