DV_VALUE

New value of the shape deformation

DV_FILENAME

Provide a file of surface positions from an external parameterization.

More in config_template.cfg: For DV_KIND = SURFACE_FILE: With SU2_DEF, give filename for surface deformation prescribed by an external parameterization. List moving markers in DV_MARKER and provide an ASCII file with name specified with DV_FILENAME and with format: GlobalID_0, x_0, y_0, z_0 GlobalID_1, x_1, y_1, z_1 … GlobalID_N, x_N, y_N, z_N where N is the total number of vertices on all moving markers, and x/y/z are the new position of each vertex. Points can be in any order. When SU2_DOT is called in SURFACE_FILE mode, sensitivities on surfaces will be written to an ASCII file with name given by DV_SENS_FILENAME and with format as rows of x, y, z, dJ/dx, dJ/dy, dJ/dz for each surface vertex.

DV_UNORDERED_SENS_FILENAME

File of sensitivities as an unordered ASCII file with rows of x, y, z, dJ/dx, dJ/dy, dJ/dz for each volume grid point.

  • Type: string
  • Default: string("unordered_sensitivity.dat")
  • In config_template.cfg: DV_UNORDERED_SENS_FILENAME= unordered_sensitivity.dat
  • Used in 1 test case file, for example: NACA64206.cfg (unordered_sensitivity.dat)
  • Code: CConfig.cpp line 2594

DV_SENS_FILENAME

File of sensitivities as an ASCII file with rows of x, y, z, dJ/dx, dJ/dy, dJ/dz for each surface grid point.

  • Type: string
  • Default: string("surface_sensitivity.dat")
  • In config_template.cfg: DV_SENS_FILENAME= surface_sensitivity.dat
  • Used in 1 test case file, for example: NACA64206.cfg (surface_sensitivity.dat)
  • Code: CConfig.cpp line 2596

DV_SENSITIVITY_FORMAT

I/O format for output plots.

More in config_template.cfg: Format for volume sensitivity file read by SU2_DOT (SU2_NATIVE, UNORDERED_ASCII). SU2_NATIVE is the native SU2 restart file (default), while UNORDERED_ASCII provide a file of field sensitivities as an ASCII file with name given by DV_SENS_FILENAMEand with format as rows of x, y, z, dJ/dx, dJ/dy, dJ/dz for each grid point.

  • Type: one of the values below
  • Values: SU2_NATIVE, UNORDERED_ASCII
  • Default: SU2_NATIVE
  • In config_template.cfg: DV_SENSITIVITY_FORMAT= SU2_NATIVE
  • Used in 1 test case file, for example: NACA64206.cfg (SU2_NATIVE)
  • Code: CConfig.cpp line 2598

HOLD_GRID_FIXED

Hold the grid fixed in a region

HOLD_GRID_FIXED_COORD

Coordinates of the box where the grid will be deformed (Xmin, Ymin, Zmin, Xmax, Ymax, Zmax)
