Hi

I hope someone is able to help me with a model I am trying to run. My problem is this.

One pipe 1m long with a given diameter. This pipe contains a certain fluid, properties known that will undergo a solidifcation and melting process. In the center of this pipe is another pipe which has water flowing through it at a given temperature. I can't seem to set this up in Fluent.

The water pipe doesnt seem to be a problem (if i was modelling just the water) set an inlet, outlet and wall BC's. For the other pipe I have I wall condition but how do I define the fluid within that pipe? There doesnt seem to be the option to do this?

Thanks in advance for any help you might be able to provide.

Billy

I am not sure, but thread should be some option in the cell zone panel to hook the fluid material.

in Gambit you can specify a continuum.
Just pick your volume and define it separately as the other one.
Later you will be able to affect your water on this continuum (Fluent side)

I have modelled it in Gambit. Using workbench, I have imported an IGES into design modeller, meshed using workbench and then loaded into Fluent?

How would I go about doing this now?

Thanks

If you modelled it with Gambit, then export your mesh file (*.msh) and read it from Fluent

Sorry, typo on my behalf. I have modelled it in the CAD program NX, exported as an IGES and then imported into design modeller.

Thanks

No experience with design modeller.
Sorry

what about the meshing ability within workbench? I can define regions in there?

No one seems to know anything about how to use these two programs or if they do they are very secretive!
