Entropy Calculations with Fluent
 

Hello,May you have a nice Day a head.

I am new user of Fluent Coding and UDf programming and i need your help for my case.May be my case is simple for you guys so kindly help me out and give me urgent help i will be very thankful to you guys.

My problem is that I need to find Entropy due to heat and Friction seperatly by the equations which i have attached over a flate plate having 3d domain.
As i have done a lot of research on this and uptill now i got an idea that it can be found with custom field function of Fluent by writing an equation in it.But i am not able to write that equation plus i also need to know how to get temperature gradients values that will be further used in the custom field function?

Kindly Help me Briefly i am really thankful to you guys for help.
