Hello everyone, I am using Python to create a RGP file, I am using the following commands that have been suggested by ANSYS to create such file. But I get the error: No module named pyExt.RefProp. I have installed all the pip packages in Python but I still get this error. Can anyone help me to understand how I can solve this problem?

Python commands:

import pyExt.RefProp as arp
fluidsPath = arp.getFluidsPath()
mat = arp.RefPropLib()

fluidList = ['fluids/water.fld']
mat.setup(fluidsPath, fluidList)

interpError = 1.0e-3
Tmin = 300.0
Tmax = 700.0
Pmin = 100000.0
Pmax = 25000000.0

# Generate both the liquid and vapor components, independent settings possible
h2ollow = arp.RGPLiquid("H2OL", Tmin, Tmax, Pmin, Pmax, interpError)
h2ollow.setMetastable(False)
h2ovlow = arp.RGPVapor("H2OV", Tmin, Tmax, Pmin, Pmax, interpError)
h2ovlow.setMetastable(False)
arp.generateRGPfile("H2O-low.rgp", h2ollow, h2ovlow)

# Generate both the liquid and vapor components in the RGP file in one go
h2omed = arp.RGPSettings("H2O", Tmin, Tmax, Pmin, Pmax, 1.0e-4, arp.ADAPT_AUTO_TP)
arp.generateRGPfile("H2O-med.rgp", h2omed)

# Generate just the vapor component in the RGP file, for entire range
h2ovapor = arp.RGPVapor("H2OV", interpError)
arp.generateRGPfile("H2O-vapor.rgp", h2ovapor)
