Question

Older Mathcad file conversion

I have some old Mathcad files I downloaded.  The are Peng Robinson based files and would do bubble point pressure, dewpoint pressure and temperatures.  They can be useful, but I have no means to update the files to the present Mathcad.

Converted to Prime 2: best tyo check the performance against known data to ensure no oddities.

Is there any guideline to use these files, e.g.( for azeotropic mixtures, for mixture with components with very different boiling point ? ), because it seems to me that their usage is not straightforward.

Furthermore there are similar files also for LLE calculations?

    Thank you Vladimir,

    In extending the files to calculate all the bubble-dew curves as basis for VLE data fitting , and I found some  convergence issues.
