Hi,
For a test-case, I was hoping to do the following: - Deform an airfoil, using a sum of multiple Hicks Henne deformations (SU2_DEF) - Compute the direct and adjoint solution (SU2_CFD) - Get the gradient of the drag with respect to the deformations (SU2_DOT) So far, this seems to work for a single Hicks Henne deformation, when the .cfg file contains: DV_KIND= HICKS_HENNE DV_PARAM= [ 0 , 0.5 ] DV_VALUE= 0.1 However, would it be possible to combine multiple deformations? I tried: DV_KIND= HICKS_HENNE DV_PARAM= [ [0,0.5] , [1,0.5] ] DV_VALUE= [ 0.1 , 0.1 ] but this doesn't seem to work. Thank you very much for your help! |

Hi jack1980,
the syntax is for multiple design variables is DV_KIND=HICKS_HENNE, HICKS_HENNE, ... DV_PARAM = (0.0, 0.05); (0.0, 0.1); ... DV_VALUE= 0.5, 0.5, .... |

Hi all,
I am trying out a similar test-case as Mr. Jouke. But in my case the only change being multiple FFD_CONTROL_POINT instead of HICKS_HENNE. DV_KIND= FFD_CONTROL_POINT, FFD_CONTROL_POINT, ... DV_PARAM= (SCB1, 0, 0, 0, 0, 0, 1); (SCB1, 0, 0, 1, 0, 0, 1); .. DV_VALUE= 0.2, 0.2, 0.2, .. But the syntax mentioned above doesn't seem to be working for me. On running SU2_DOT_AD I am getting the the following error: [localhost:07682] *** Process received signal *** [localhost:07682] Signal: Segmentation fault (11) [localhost:07682] Signal code: (128) [localhost:07682] Failing at address: (nil) [localhost:07682] [ 0] /lib64/libpthread.so.0(+0xf5d0)[0x7f7b143da5d0] [localhost:07682] [ 1] SU2_DOT_AD[0x67546e] [localhost:07682] [ 2] SU2_DOT_AD[0x65128d] [localhost:07682] [ 3] SU2_DOT_AD[0x671c96] [localhost:07682] [ 4] SU2_DOT_AD[0x41e10a] [localhost:07682] [ 5] /lib64/libc.so.6(__libc_start_main+0xf5)[0x7f7b14020495] [localhost:07682] [ 6] SU2_DOT_AD[0x53bbee] [localhost:07682] *** End of error message *** I am using SU2 6.0.0 "Falcon". Thank you very much for your help! |
