Temperature subroutine in PHOENICS 3.5

October 28, 2003, 16:12

Hi,

Is there anybody running a simulation using PHOENICS 3.5? If you are using the PHOENICS commander, have you ever successfully call a temperature subroutine from a Ground.for file (where temperature is calculated here)and can get the correct temperature values? My program can run in PHOENICS 3.4 but failed in PHOENICS 3.5. Could anybody share with me what are the things that i maybe need to pay attention of if you have overcome this before. Thank you in advance.

In the Ver3.5 the definition of Cp has been changed.

You can get the imformation about from What's new in Version 35.

Yeah, i do aware of that, thanks. Anyway, do you have any examples for it?

The definition for Cp has been changed in PHOENICS 3.5, where internally it is defined by PHOENICS where T=(h-h_base)/Cp. By using our previous equation (prior to version 3.5) which is given by -(k/Cp).grad(h) for conduction term, we defined only the value of the term (k/Cp), now in PHOENICS 3.5, how can we calculate this k value? Do we need to calculate this value?

Thank you for any volunteer trying to help me.
