Hi,
Is it possible to deform all FFD control points by a specified amount (i.e. a unit deformation in y) to visualise whether they are set up correctly and properly mapped to the geometry. I think it might be possible using the SU2_DEF command but I cant figure out what options to set in the .cfg file, Cheers, M. |

Mike,
Yes it is. After setting up the FFD box and creating the new mesh with the FFD information, you need to create a new .cfg. In this .cfg, for the DV_KIND option, there must be one entry of "FFD_CONTROL_POINT", separated by commas, for every control point you want to move. There must also be the same number of entries with the appropriate format, separated by semicolons, for DV_PARAM. The last three numbers of the DV_PARAM entries specify the scale of the movement in the x, y, or z direction. Next, under DV_VALUE, a displacement must be input for each point, separated by commas. Finally, DEFINITION_DV should contain an entry for all of the points you wish to move, where the last three numbers indicate the movement constraints. ex.(0,0,1) means movement only in z. Max |
