Revision 2266 - (view) (download) (as text) (annotate) - [select for diffs]

Diff to previous 2262
The (p,h) function is converging almost everywhere. The home-made Newton iteration wasn't starting well for supercritical states
when the starting guess had rho = rho_c, so changing slightly away from fixed almost all the problems.

Deleted sat2.c and sat2.h, that code is not being used anywhere in ASCEND/FPROPS now. REFPROP algorithm replaced by Akasaka approach.
Moving sat3.c code into sat.h.

First attempt at Akasaka algorithm. But something's badly broken in the test suite, need to go find what.

Adding bespoke (p,h) iteration code, but looks like some errors with the partial derivatives.

For some reason the fdfsolver is not varying the guess values...
