Talk:FPROPS

Ideas for improved API for FPROPS... for discussion

• Use of FPROPS from Python is currently not intuitive (especially compared with freesteam). Much better approach arises from object-oriented approach, eg something like

• What gets stored in these 'state' objects for pure components?
  • pointer to 'fluid' object
  • T
  • rho
  • rho_f, where already evaluated
  • rho_g, where already evaluated
  • p_sat, where already evaluated

• What gets stored in the 'fluid' objects?
  • EOS data
  • any precalculated data not contained in the source data file (eg p_c, rho_f_t, possibly other stuff)

• What about 'mixture' objects?
  • pointers to 'fluid' objects
  • mass fractions? or should those be in a 'mixturestate object??

• How do we deal with chemical reactions, and changing mass fractions... can we handle that? What is the mechanism?

This looks good, is there a book or tutorial about writing python bindings? I've never played with bindings before and this is the best I could find on google... RichardTowers 11:04, 27 May 2011 (UTC)
