Thanks a lot .anon_a,I have another question:after conduct snappyhexmesh,i should conduct the solver in which time .Tank you very much.

If I understand correctly, you are wondering about the startTime that you must use after running sHM, because it produces several time directories. In fact, these directories contain the mesh in different stages.

I can think of the following two options: You may use "latestTime" in controlDict so that it uses the most complete version of the mesh (the last time directory). Or, you can call sHM with "snappyHexMesh -overwrite" so that the mesh is overwritten and you only have the initial conditions directory. In the latter case, you can use "startTime" in controlDict, as always.

I always choose the second option to avoid confusion, unless I only want to check the differences between various grid stages.

You understand my question very correctly.If i choose the first opioion,i think i should copy some folder to the latest time folder.right?this folder should contain 0 folder.I hope you can give my fault.Thanks a lot.
