I am using a new version of FLUENT (6.2.16)

The old command

>file reread-grid

no longer seems to work.

This command was used when you had already developed and run a model and then wanted to import a new grid from GAMBIT without wiping out all your boundary conditions material properties etc.

Needless to say there is nothing in the Fluent help manuals on this.

I'm not familiar with the reread-grid in previous versions of Fluent 6 - although I have used a similar approach in versions 4 of Fluent.

To do the same thing in version 6, you can use the File->Interpolate to write data from your current model along with write-bc (boundary conditions), which also saves the various models associated with the case.

Then, you can read in a new Gambit grid, read-bc to get the same model set-up, and then read the data from the interpolated file. Not sure if this what you are looking for, but it is not too painful.

That doesn't sound quite like what I am looking for.

Let me restate.

You develop and run a fluent/gambit model.

You go back to gambit and change the mesh.

How to read the new mesh into fluent without wiping out and having to re-input your boundary conditions and material properties.

The answer (thanks to Jonas larson) seems to be

file write-bc

grid zone replace (not "read case" as this deletes properties and solver parameters

file read-bc

So, three commands to replace the single command file reread-grid

That's what I call progress

Well I think the progress is being made:

in the Grid Menu , go to the Zone option, that is Grid->Zone Here you will see a lot of options like [*] append case[*] replace etc etc

If you explore the whole thing on the TUI, it might give you much much more flexiblity than you want it.

I just had a look for 5 minutes, it seems okey to me.

Have a look it might be the solution the probs.
