When defining Named Selections, you can use the Send to Solver option to control whether a Named Selection is passed to the solver. Send to Solver is available in both the Mechanical and Meshing applications.

The default is Yes for Named Selections that you create, and No for Named Selections that are generated automatically by the Mesh worksheet. When set to No, the selected Named Selection is not passed to Ansys Fluent, Ansys CFX, Polyflow, CGNS, Ansys ICEM CFD, Ansys Fluent Meshing, Mechanical APDL, Ansys Autodyn, or any other downstream system that may be connected to the Mechanical or Meshing application.
