Hi everybody,
as the title stats i want to run every snappyHexMesh phase separately in order to use a dict specific for each step. I want to do so because i need to specify three different meshQuality dicts in order to better control the mesh generation process. My problem is that snappyHexMesh seems not to recognize the mesh he has generated before. For instance if i run just the castellated phase (saved in the 0.0001 directory) with his dict and then the snap phase (saved in the 0.0002 directory), the latter will try to snap the blockmesh (saved in the constant directory) instead of the castellated mesh. Does anyone knows how to force snappy to use the correct directory? Thanks for the patience |

Hi!
1. Try with "startTime LatestTime;" in the controldict. I don't know if it works but there is no arg for this in snappy so i think this is the way to do. 2. If not, then just rename the directory to 0 where you wanna start. 3. Or just run snappy with the -overwrite switch so you will have your mesh in the 0 time always. I'm not sure if 1 and 2 are working, but 3 must be ok. |

In foamExtend 4.1, when we do snappyHexMesh -overwrite, it keeps on asking alpha1 file for each and every time step. From other threads, I came to know that extend versions have issues with sHM. even generating the eMesh by
