| Summary | 0003792: SnappyHexMesh Error: malloc(): Invalid next size (unsorted) | ||||
| Description | Hi, all, I met a problem when using snappyHexMesh to generate mesh. What I try to do is to subtract a cylinder from a block using snappyHexMesh. It runs well when the number of background mesh, which is generated by blockMesh, is lower than 100 million. When the total number of grids increases to more than 100 - 300 million, snappyHexMesh always crashes at "Shell refinement iteration" and show error messages: Foam::error::printStack(Foam::Ostream&)malloc(): invalid next size (unsorted) Moreover, sometimes the error becomes "Segmentation error". Initially, I thought it might be lack of RAM but I increased RAM to 3600 Gb, the problem still exists. | ||||

Have you compiled OpenFOAM with 64bit labels? |

Hi, Henry, Thank you for your reply. I am using Docker version OpenFoam 8.0 and mesh generation & CFD computation run normally for the cases with mesh number less than 100 million. When I increase the number of background mesh, the problem occurs. Kind Regards, |

To create a mesh that large you will need to compile OpenFOAM with 64bit labels. |
