[Commercial meshers] Separating regions Problem after importing from Fluent Mesher

peterhess · March 1, 2016, 07:42

Hello everybody,

I imported a multi-Regions Mesh from Fluent (Ansys) Mesher via command:

fluent3DMeshToFoam

It works well until here...

To separate the regions from each other I used the command:

splitMeshRegions -cellZones -overwrite

This one made also the job partly done.

The Problem is, after using this command, all the regions, that are physically separated, has been also separated and named separately...

Actually, some of them belongs to the same region and have also the same name by importing and are connected to the same neighbours...

- Should the command not collect them (the regions with the same name during importing) to one region? How could I fix that?

- How could I recollect those regions to just one again?

Thanks for your support

Peter

Using the command:

splitMeshRegions -cellZonesOnly -overwrite

solved the problem.

This command seems to separates the regions by name and not by walking through and searching the connection between the regions...

thanks

Peter
