Hi all,
I am trying out the following test-case: - Deform an airfoil (SU2_DEF) - Compute the direct and adjoint solution (SU2_CFD and SU2_CFD_AD) - Get the gradient of the drag with respect to the deformations for multiple FFD_CONTROL_POINT (SU2_DOT_AD) I am trying the following syntax: 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, .. 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! |

Hi Mardar572,
Can you explain more in depth your issues? Are you using v6.2? If so, you should migrate to v7.4 as is it the most up-to-date. |

Hi wallym,
I have two computers. One is ubuntu other ıs centos. They have exact same installation of SU2 7.4.0. Ubuntu can run the following tutorial without any problem. https://su2code.github.io/tutorials/...ained_ONERAM6/ However, centos has a problem while running SU2_DOT_AD. As follows: HTML Code:
---------- Start gradient evaluation using sensitivity information ---------- Evaluate functional gradient using Algorithmic Differentiation (ZONE 0). 1 Free Form Deformation boxes. 1 Free Form Deformation nested levels. FFD box tag: WING. FFD box level: 0. Degrees: 10, 8, 1. FFD Blending using B-Splines. Order: 0, 0, 0. Number of parent boxes: 0. Number of child boxes: 4836. Segmentation fault (core dumped) Thanks |

Hmmm, I don' think I can help here. Could you post the SU2 github? This issue should get more traction there.
Thanks |
