multi domain heat transfer prob
 
We are solving a multidomain heat transfer model to find out the heat transfer characteritics between hot fluid and a cold fluid.

our prob is that we have defined different materils for each domain but CFX is taking into considration only one material. i.e if we have defined water as the material for cold domain and air as the material for hot domain, while defining physics it is taking into account only one material. if we take water first the same material is automatically taken by the hot domain as well.

any body can help solve the prob

Set the environement variable:

CFX5_NO_CONSTANT_PHYSICS=T

Now when you run CFX-Pre it will not force the same fluids to be used in all domains. Mike
