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

 September 19, 2011, 07:47 #5 New Member   Join Date: Aug 2011 Posts: 10 Rep Power: 7 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.

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.
