Hello everyone,
I encountered a "double free" message when i am evaluating fixed CL RANS simulation. I have tested three cases to see when does this error occur. The first case is a RANS simulation for CRM wing. My configure file is opt_crm.txt in the attachment. In this case, when I set FIXED_CL_MODE= YES, then in the end of the SU2_CFD execution, it will return messages below: Code:
Writing comma-separated values (CSV) surface files. Merging coordinates in the Master node. Merging solution in the Master node. Writing SU2 native restart file. Writing the forces breakdown file. *** Error in `SU2_CFD': double free or corruption (!prev): 0x0000000007dc2aa0 *** ======= Backtrace: ========= /lib/x86_64-linux-gnu/libc.so.6(+0x777e5)[0x7fbaa7b177e5] /lib/x86_64-linux-gnu/libc.so.6(+0x7fe0a)[0x7fbaa7b1fe0a] /lib/x86_64-linux-gnu/libc.so.6(cfree+0x4c)[0x7fbaa7b2398c] SU2_CFD[0x8553d5] SU2_CFD[0x855c59] SU2_CFD[0x7583c2] SU2_CFD[0x75ceb5] SU2_CFD[0x40759c] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0)[0x7fbaa7ac0830] SU2_CFD[0x735109] ======= Memory map: ======== 00400000-00d07000 r-xp 00000000 08:28 1068882 /home/wanghao/software/SU2-5.0.0_me/bin/SU2_CFD 00f06000-00f2d000 r--p 00906000 08:28 1068882 /home/wanghao/software/SU2-5.0.0_me/bin/SU2_CFD 00f2d000-00f30000 rw-p 0092d000 08:28 1068882 /home/wanghao/software/SU2-5.0.0_me/bin/SU2_CFD 00f30000-00fc2000 rw-p 00000000 00:00 0 02c42000-1e248000 rw-p 00000000 00:00 0 [heap] 7fba8c000000-7fba8c021000 rw-p 00000000 00:00 0 7fba8c021000-7fba90000000 ---p 00000000 00:00 0 7fba913ec000-7fbaa516c000 rw-p 00000000 00:00 0 7fbaa516c000-7fbaa51ad000 rw-s 00000000 00:14 80 /dev/shm/mpich_shar_tmphYlQha (deleted) 7fbaa51ad000-7fbaa51ee000 rw-s 00000000 00:14 71 /dev/shm/mpich_shar_tmpJXXyK4 (deleted) 7fbaa51ee000-7fbaa522f000 rw-s 00000000 00:14 65 /dev/shm/mpich_shar_tmpqe47BR (deleted) 7fbaa522f000-7fbaa550c000 rw-p 00000000 00:00 0 7fbaa*** Error in `SU2_CFD': double free or corruption (!prev): 0x0000000006243650 *** 550c000-7fbaa5517000 r-xp 00000000 08:21 262591 /lib/x86_64-linux-gnu/libnss_files-2.23.so 7fbaa5517000-7fbaa5716000 ---p 0000b000 08:21 262591 /lib/x86_64-linux-gnu/libnss_files-2.23.so 7fbaa5716000-7fbaa5717000 r--p 0000a000 08:21 262591 /lib/x86_64-linux-gnu/libnss_files-2.23.so 7fbaa5717000-7fbaa5718000 rw-p 0000b000 08:21 262591 /lib/x86_64-linux-gnu/libnss_files-2.23.so 7fbaa5718000-7fbaa571e000 rw-p 00000000 00:00 0 7fbaa571e000-7fbaa7aa0000 rw-s 00000000 00:14 49 /dev/shm/mpich_shar_tmp1WxrYH (deleted) 7fbaa7aa0000-7fbaa7c5f000 r-xp 00000000 08:21 262587 /lib/x86_64-linux-gnu/libc-2.23.so 7fbaa7c5f000-7fbaa7e5f000 ---p 001bf000 08:21 262587 /lib/x86_64-linux-gnu/libc-2.23.so 7fbaa7e5f000-7fbaa7e63000 r--p 001bf000 08:21 262587 /lib/x86_64-linux-gnu/libc-2.23.so 7fbaa7e63000-7fbaa7e65000 rw-p 001c3000 08:21 262587 /lib/x======= Backtrace: ========= *** Error in `SU2_CFD': double free or corruption (!prev): 0x0000000007959770 *** 86_64-linux-gnu/libc-2.23.so 7fbaa7e65000-7fbaa7e69000 rw-p 00000000 00:00 0 7fbaa7e69000-7fbaa7e7f000 r-xp 00000000 08:21 267380 /lib/x86_64-linux-gnu/libgcc_s.so.1 7fbaa7e7f000-7fbaa807e000 ---p 00016000 08:21 267380 /lib/x86_64-linux-gnu/libgcc_s.so.1 7fbaa807e000-7fbaa807f000 rw-p 00015000 08:21 267380 /lib/x86_64-linux-gnu/libgcc_s.so.1 7fbaa807f000-7fbaa8187000 r-xp 00000000 08:21 262585 /lib/x86_64-linux-gnu/libm-2.23.so 7fbaa8187000-7fbaa8386000 ---p 00108000 08:21 262585 /lib/x86_64-linux-gnu/libm-2.23.so 7fbaa8386000-7fbaa8387000 r--p 00107000 08:21 262585 /lib/x86_64-linux-gnu/libm-2.23.so …… Then i tried an invisid test case, this case is orriginally from the TestCases folder of SU2 (TestCases/euler/naca0012). In this case, SU2 works well for both FIXED_CL_MODE and FIXED_AOA_MODE. Finally, i tried another tutorial case for NACA0012 (from /TestCases/rans/naca0012), then SU2 has the same problem in FIXED_CL_MODE as in the first case. opt_crm.txt inv_NACA0012.txt turb_NACA0012_sst.txt For info, i attached all the configure files for all three cases. I am using UBUNTU 16.04, build SU2 with parallel build mode. I also tried AD build mode, and it has the same problems. Hoppfully someone could help me with this. Thank you! |

Hi Wang Hao,
I also noticed this problem when I run flow or optimisation cases using SU2 V5.0. Please refer to this thread: Segmentation fault in SU2 V5.0 For inviscid cases, the fixed CL mode works successfully; however, for viscous cases, segmentation fault occurs either for flow analysis or optimisation cases. The problems are quite similar to yours. Guangda Yang |
