how to use refprop with mixtures

How do I use Refprop for mixtures?

Issuing a command

C3H8Tables = twoPhaseFluidTables([-195,800],[0.00001,10],50,50,150,'R401A','C:\Program Files (x86)\REFPROP')

fails to find the mixture file R401A.MIX

There is a file int eh REFPROP/MIXTURE folder labled R401A.MIX

C3H8Tables = twoPhaseFluidTables([-195,800],[0.00001,10],50,50,150,'Propane','C:\Program Files (x86)\REFPROP')

works. The file PROPANE.FLD is found and calculations are performed.

Hi Ray Joseph,

Any luck in solving this?

It should be written '*.mix'

Thanks Baqer, putting .mix at the end of the name of the fluid worked for me e.g. 'r454b.mix'.

I have a question: how can I create a twophasefluidtable for the mixture r600(0.11)/r600a(0.89) (or for any mixture) using coolprop or refprop?

I have already created the tables for both R600 and R600a... It would be helpful if someone can guide me with this either using CoolProp or Refprop. Thanks
