TUI for material properties

nenazarian · July 26, 2012, 15:21

Hi

I want to define new material properties that are not in fluent database using TUI but Im just wondering in a loop and cant properly do that.
Can someone plz help me ?

Right now I need to define 3 new material and in my further steps of simulation I need to change some of their properties. So maybe I should save a file and edit that and have a TUI command to read that saved file.

Anyway Im not able to do any of these options.

Appreciate your help.
Cheers

Hi Negin,
To create a new material (liquid replaces air) I use this - I only change density and viscosity:
define materials change-create
air
liquid
yes
750
n
n
yes
0.02
n
n
n
yes

Hi

Thank you for your response.
The only problem is that this only works if the material-name is in the fluent data-base (such as air)
however, Im defining some material properties using user-defined database option.
Any suggestion on that?

Cheers

I think you didn't understand the commands:
I replace "air" (which is the default in Fluent) by a material called "liquid", which is not in the Fluent database, and for this new material I define a new viscosity and desity.

Oh I just figured it out.
Thank you so much for your help.
