Hi

In the 3D shape optimization using FFD box deformation,
the parameter 'scale' in the DEFINITION_DV is defined as scale of the variable.

FFD_CONTROL_POINT ( 7, Scale | Mark. List | Chunk, i_Ind, j_Ind, k_Ind, x_Mov, y_Mov, z_Mov )

What does it signify?

Thanks

Hey Anant,

This is a scaling factor by witch SU2 will multiply the design variable before sending to the optimizer.

Hi Trent

Thanks for the reply.

I wanted to know how should we choose this parameter for a given
problem ?

Does it depend on the mesh conversion factor or the scale factor with which
the objective function is multiplied ?

Thanks
Anant
