Out of the solvers available like MUMPS, PARADISO, SPOOLES, etc. which is best suited for solving highly non-linear problems
As i heard from my colleague that spooles is suited for this types of problems although i didnt work on this kind of problem yet.
I would recommend to you the Back Shoting Method. It works fine for highly non - linear problems. I attached the file for your convinience.
B-Spline method is best yet.
It can be understood by intuition that gases can't be compressed at constant pressure or constant volume. But what is the thermodynamic reason behind it?
