Creating ew material's properties.

foo7 · September 19, 2011, 05:20

Hello there.

Well, I'd like to know if it is possible to add new material properties, created by myself.

Thanks!

Yes. Duplicate an existing material in the tree and edit it.

Sorry, I guess I didn't make myseof clear. What I want is to create a new property for all materials. In a way that I could call it within CEL. For example, I would create a property called PROPERTY_x, açd within CEO I would be able to write: Fluid 1.PROPERTY_x

You cannot do this.

What is the property you wish to add?

I'm trying to simulate a gas mixture, formed by a few different gas components.
Each component's heat capacity is modeled by the following equation: a + b*T +c*T^2. In which T is the gas phase temperature and a,b and c are coefficients which vary from component to component.

So to have all the components heat capacity calculated I'd have to write the equation for each one of them. What I would like to do is create a set of material properties in which I could store the values of the parameters a,b, and c. And then call them in CEL. This way I would only need to write the equation once.

Sorry, you cannot do this in CEL.

I would simply put the equation a+b*T+c*T^2 in as the heat capacity for each component, with the parameters substituted for a, b and c. Not very elegant but simple and CEL can handle it.

Also this sort of update is easier to do in the expression editor rather than the CFX-Pre GUI. That way you can easily copy and paste sections of CCL and CEL rather than zillions of clicks.
