Setting up Freeform Scaling Scheme in Adjoint Solver

How to set the freeform scaling scheme in adjoint solver design tool in the Ansys Fluent?

The Freeform Scaling Factor, along with the freeform scaling scheme, controls how the overall scaling factor for the design change magnitude is interpreted

• Control-point spacing: the magnitude of the freeform deformation will be based on the control-point spacing, i.e. a Freeform Scale Factor of 1.0 leads a to maximum control point movement on the order of one sub-cell of the control volume. The sub-cell size is determined by a uniform sub-division of the morphed region based on the number of control points specified. A value of 1.0 is a reasonable default to preserve mesh quality during the morphing process.
