Dear Sir,


Dear Sir,

My model is square shape, 2D , simple model .The pink colour represent the reaction between reactant(e.g.glycerol with steam) , with the product (e.g. as hydrogen , carbon monoxide & carbon dioxide). I had key in the reactants & the products already by selecting:

->define
->materials
:name the each reactants & products
-Selecting material type : mixture
-Fluent mixture material : mixture-template
-key in all the reactants & products in properties (mixture species : name)
-key in number of mole for each reactant & product in properties(reaction:finite rate)

All the reactants & products can be obtain from the fluent database.

The red one represent the catalyst. I need to create the catalysts (e.g platinum-titanium oxide , platinum-silicon oxide and platinum-aluminium oxide ) . How should I do it?

CAn I directly change the mesh size in the gambit file ,than convert to mesh file ,to be open in fluent software??

Hi Mel, when you create this model in ProE or any other CAD package, make sure the model matches the accuracy of gambit, i.e. dimension decimal places run to 10^-6 or below. If you do not do this then you will find gaps in between extrusions and will waste a lot of time creating virtual elements.
If you're not sure how to do this reply to me by private message, I can help with ProE. Catia does this by default.
