Dear All, About 3 weeks ago I made an update in my computer and after that installed the last version of Nektar in the repository without problem. However, after this installation when I tried to run an analysis with an xml file including Curved edges I got the following error: Initial Conditions: - Field u: 0 - Field v: 0 - Field w: 1 - Field p: 0 Writing: "Re100_v11_2_0.chk" [Dell-Workstation:56500] *** Process received signal *** [Dell-Workstation:56500] Signal: Segmentation fault (11) [Dell-Workstation:56500] Signal code: Address not mapped (1) [Dell-Workstation:56500] Failing at address: 0x9a1b000 [Dell-Workstation:56500] [ 0] /lib/x86_64-linux-gnu/libc.so.6(+0x36c30) [0x7f5d2d442c30] [Dell-Workstation:56500] [ 1] /usr/lib/libblas.so.3(dgemm_incopy_NEHALEM+0x39e) [0x7f5d2e9a979e] [Dell-Workstation:56500] *** End of error message *** Segmentation fault (core dumped) What may be the reason for this error?
