No component with name...

Hi.
I think the error is due to the component names. See available components in this file:
https://github.com/equinor/neqsim/blob/master/src/main/resources/neqsim_component_names.txt

Try to run the following code:

from neqsim.thermo import fluid,fluid_df,TPflash,printFrame
import pandas as pd

gas = {"methane": 95, "nitrogen": 1, "CO2": 0.2, "ethane": 1, "propane": 0.6, "n-butane": 0.3, "n-pentane": 0.08, "n-hexane": 0.4, "oxygen": 0.05}

fluid = fluid('srk')
for key in gas.keys():
    fluid.addComponent(key, gas[key], "mol/sec")

fluid.setTemperature(320.0, 'K')
fluid.setPressure(10.0, 'bara')
TPflash(fluid)
printFrame(fluid)

#Alternative way of creating the fluid

naturalgas = {'ComponentName':  ["nitrogen", "CO2", "methane", "ethane", "propane", "i-butane", "n-butane", "i-pentane", "n-pentane", "n-hexane"], 
        'MolarComposition[-]':  [0.34, 0.84, 90.4, 5.199, 2.06, 0.36, 0.55, 0.14, 0.097, 0.014]
} 

naturalgasdf = pd.DataFrame(naturalgas) 
naturalgasFluid = fluid_df(naturalgasdf)

naturalgasFluid.setTemperature(320.0, 'K')
naturalgasFluid.setPressure(10.0, 'bara')
TPflash(naturalgasFluid)
printFrame(naturalgasFluid)

Thank you very much for the reply. Indeed, I think it was also not correct before, but as I did not get a feedback from neqsim, I did not noticed that something was wrong.

I guess the fact that I am now getting an error message is because of the new Java bridge since v. 2.3.0. Thanks for that, it is useful to get feedback from the tool.

And thanks for the alternative method to create a fluid.
