[snappyHexMesh] The mesh has distorted to it original

kelvinaaa · December 3, 2019, 20:03

Hello All,

I am newbie to use openfoam. I am now generating mesh using snappyHexMesh. Below are two photo before and after snappyHexMesh.

before snappyHexMesh

after snappyHexMesh

The mesh shape has distorted to its original one. Can anyone help to see what happens and how to resolve this problem? Thanks.

Regards,
Kelvin

- if you use SHM without its `feature edge` functionalities, SHM will not snap to those sharp edges. therefore, please google `feature edge`, `extended feature edge` keywords to obtain further info
