2-D Meshing
This chapter includes material from the book Practical Finite Element Analysis. It also has been
reviewed and has additional material added by Matthias Goelke.

8.3 Maxwell Relations
The fundamental property relations are written so that the left-hand side is the differential of
a state function as follow
dU = TdS PdV
(8.3-1a)
dH = TdS + VdP
(8.3-1b)
dA = SdT PdV
(8.3-1c)
dG = SdT + VdP
