Hi everyone,
I'm trying to run a test with R-513a, which doesn't currently exist on the 2P fluid properties block, however, the two fluids which it is a mixture of R-1234yf and R-134a do. Is there a way to leverage the twoPhaseFluidTables function to add this particular refrigerant to simscape for testing?

Hi @Netzahualcoyotl,
I think it's possible. I just created a R-1234yf/R-134a 50/50 mixture in REFPROP, saved it as "newMixture", then the twoPhaseFluidTables was able to use it!!!
props = twoPhaseFluidTables([100,400],[0.01,2],25,25,60,'newMixture','C:\Program Files (x86)\REFPROP 10.0\')
Give it a try. Hope it works for you, too. I believe Coolprop allows new fluid definition, too. My first time trying this as well :)
