Help for Finite Volume Code for 2D Heat transfer in Cylindrical Coordinate
 

I am trying to write a finite volume code for 2-D heat transfer equation in the cylindrical coordinate by finite volume method. I have used the methods provided in Hoffman's CFD book, but I found descriptions of this book slightly unclear. I think this book is not appropriate for coding and just describe the method. Is it possible to introduce a conclusive and concise reference to me for coding finite volume method? Unfortunately I have not enough time, so the reference should be concise!!! ;)
Thanks in Advance
