comment Interactive steam tables and phase diagrams in Mathematica
@VitaliyKaurov Yes. I was thinking that. It would be quite an exercise extracting points though. Something I'll put my mind to on leaner days! Thanks!

@VitaliyKaurov May I give credit to your important contribution to this answer (by linking this answer in my course webpage) when I discuss this with my students?

I would like to purchase one if it is affordable. ($50 +/-)

@ssch To be specific steam table data - enthalpies, entropies, internal energies, saturation pressures/temperature.

@belisarius Sense of humor isn't stupid!!!! It's just dangerous....... boo! :P I think we should stop this back and forth stuff.... just for the greater good..

@VitliyKaurov Do you think I could get $P-v$ and $T-s$ diagrams instead of $P-T$ phase diagrams? I hope I am not asking for too much! :P

This is a nice answer! I'll give this question another day or so at least though... thanks!

@belisarius ? You say that like its a bad thing... :P... They are not "wannabe" engineers as that is rather derogatory. They are budding engineers. I would like to familiarize them with mathematica.

@acl a wee bit off topic but are you guys on this website the ones who built mathematica? How do you all know nearly everything about it whilst I sit around scratching my head!!!! :P

@acl, how do you plot Interpolation@Flatten[ Table[{{x, y}, 1 + .05*RandomReal[{-1, 1}]}, {x, 0, L + 1}, {y, 0, L + 1}], 1]? I tried putting it in a Plot3D function but that didn't work? Is that because its a Table now?

@acl your suggestion did work as an initial condition. I have to see what I can do about Vitaly's Spline initial condition.

comment Small random disturbance of a flat surface
@acl I think with a random number type ic, there would always be the ibcinc warning popping up. The whole SplineClosed->True helps with that. However, I am unable to use BSplineFunction in NDSolve as an ic. I was however, able to use ur suggestion with bsf = Interpolation@Flatten[ Table[{{x, y}, 1 + .05*RandomReal[{-1, 1}]}, {x, 0, L + 1}, {y, 0, L + 1}], 1]

comment Small random disturbance of a flat surface
@acl I have an inkling as to why I'm having an issue: my BSplineFunction isn't a function of x and y. How can I describe it to be a function of x and y? I think thats what NDSolve complains about when I try to use a spline surface.
