how new material which is varible canadd in ansys
 

does anyone know how new material property which is variable can be add in ansys cfx. Let me Define the problem clearly i am using new fluid and property of this new fluid is changing with respect to temperature and pressure. in my CFD simulation pressure is constant but temperature is changing from 300 to 1000 deg.and i want that during CFD simulation that variablr property should be used by cfx to get accurate result like heat transfer, density plot or any other plot. so how can i do this . thanks
