Hi guys

I have a geometry with two zones body and fluid going through it bounded in a box. I like to define the boundaries and zones in Tgrid for further analysis in Fluent, does anybody know what's the best approach, User's guide is not clear on this.

cheers,

Four boundaries:

• In the Menu bar, click Boundary
• Select the boundary to be renamed
• Check Rename
• Enter new name in Name field
• Click Apply

For zones:

• In the Menu bar, click Mesh
• Click Manage
• Select Rename
• Select the cell zone you want to rename
• Change the name
• Click Apply

Hope this helps!

Thanks for the reply, but this is true if the boundaries and zones were defined before if these zones are not defined how can I select a region form the geometry and define it as a zone or boundary?

cheers,

Generally, this is how I would recommend you proceed with TGrid: place the place the parent surface meshes in separate components 1st (preferably in a separate mesher such as HyperMesh). TGrid's native support for mesh subdivision isn't that good.

If you can't do this, import the geometry 1 boundary/zone at a time, name that boundary/zone, then import the next boundary/zone, merge nodes between it and the preceding, then rename it, etc.
