Try asking your question on http://communities.ptc.com/community/mathcad - there are few people who look at that site who are likely to be able to point you at such resources. (Mind you if you know the equations and have a basic text list of properties, writing a Mathcad worksheet to calculate them should be straightforward).

which version of Mathcad ?
I have read that there is a link with Prode Properties, see

http://communities.ptc.com/community/mathcad/chemi...

Prode has many features and it should be able to do all what you need.

If you have an Excel table, that can be read into Mathcad, so what's the problem with that? Ditto for some Matlab formats.

thanks all for the help,

delittle, I know Prode but I was not aware of the link with Mathcad 15,
seems a interesting stuff, hoping it will be available soon.

IRstuff, I need to solve iteratively, a table doesn't give the required accuracy, I could calculate the properties with a equation os state, not easy in Mathcad and the resources which I found (Mathcad files) are for pure fluids not mixtures.

Could you give a pointer to an Excel or Matlab site that does give a relevant resource? I have not encountered many instances of Excel being able to something that Mathcad can't with greater ease (apart from the tabulation and formatting). Iteration is Mathcad's bread and butter ...

hcostello, tell me exactly what properties and which species are you interested in. If you deal with water/steam and/or air/combustion gas components properties, then i can give you the answer. On a side note I can tell you that from my experience, it is generally better to have properties models in dll libraries.
