Segfault in second DSN iteration
1 Attachment(s)
Hello!
I'm attempting a shape design with a few geometric constraints using shape_optimization.py. My simulation runs fine until direct CFD is run on my_mesh_deform.su2 in DSN_002. Then I get a segfault right after ParMETIS partitions the graph. Here's a quick screenshot of the segfault message. I'm running on 60 cores with (nominally) 384GB of memory available. So I feel I should have more than enough memory available. I also tried running parallel_computation.py using the deformed mesh, and I get the same error. I noticed that the deformed grid seems very different from the initial grid. It seems like a lot of volume cells have gone missing. Screenshots before deform, and after. Is it possible that deformation merged some of the grid points? I took a look at the surface and volume deformations and didn't see much out of the ordinary but it might be hard to tell from inspection. Any ideas as to how I might resolve this? I'm hoping it's just a simple error in my config file. Thanks. |
Hi Jason,
I just opened a Pull Request that fixes that problem. It was introduced in v7.0.1, so v7.0.0 should work fine ... Next maintenance release (end of this month) will include that fix. |

Update: installing v7.0.0 does indeed resolve this issue. Thanks again!
