splitMeshRegions Error!
 
1 Attachment(s)
Hi,

Can anyone told me why I have an error when I tape this command:

Code:
splitMeshRegions -cellZonesOnly
Error

Code:
For the cellZonesOnly option all cells have to be in a cellZone.
Cell 0 at(-0.37500614 -0.37500185 -0.32501155) is not in a cellZone. There might be more unzoned cells.
I have 3 solid and one fluid in my problem (see attached picture).

Thanks.

Hi,
I have resolved a problem

This command
Code:
splitMeshRegions -cellZonesOnly
can work if I make all cells in a zone by using topoSetDict.

Thanks

Check your polyMesh directory. Now check if there is a file called cellZones. If there is open it and check how many there are, what the names are etc. Also check if you have a folder called sets. For the cellZones only option to work you need to have a cellZone for every cell in your mesh.

If there is no such file you need to create those zones with topoSet

Could you please share that topoSetDict. ? I am also facing this type of error and don't know how to solve this.

Thanks

Try with this,
blockMesh
topoSet

splitMeshRegions -cellZonesOnly -overwrite
