Meshing & Exporting a Domain of Different Sub-Volumes
 

Hello everyone,

As I said in a previous post I am working on modelling cooling of a ventilated disc brake.

I have taken a 12 degree repeating sector of the geometry which I intend to model using a rotating frame of reference.

My problem is that although I have subdivided the original geometry (imported as a step file) into various subvolumes, as you can see in my first attachment, and have managed to mesh it (poorly I know, but I am just trying for now), as you can see in my second attachment,
when I try to export it it is OK but when I import into CFX I get a reading error saying something like "premature file end".

I read somewhere that I need to link the face meshes of something to be able to have a .msh file that can be read. I really don't know what this means or how to do it.

Could someone PLEASE spare a few moments to lay down a few steps I need to follow when subdividing a volume (in case I am making a mistake there) and when meshing the separate volumes, as I don't know if I am missing a step out or if I am doing something totally wrong and messing up the .msh file.


Have a look at my attachments, it is quite critical that I manage to import to CFX soon.

Thanks in advance and I hope I can get some help.:)

Hello did you go the reason for this and had you clarified

Thank You

If you want to use "periodic" boundary condition, you will have to link face meshes which have been selected for the periodicity.
Doing that you will have exactly same surface meshes for the periodicity
