I am having almost the same exact error - I am injecting CO2 into a grid of 1x1x1 cubes covered on top by a layer of rock that has low permeability and I get those same error messages "EOS Cannot Find Parameters at Element ____" and the program reduces the time step to almost nothing. I have found the only way to get mine to work is the drop the injection rate below 10^-8 kg/s. I'm not sure how to resolve this issue - I've tried a variety of different enthalpies using methods described here and my own calculations. Any help would be appreciated.

I've been trying to model injection of CO2 into a shale layer and I'm not sure what enthalpy to input for the CO2 - I know what pressure and temperature I'd like it to be, but without a reference enthalpy state for CO2 I'm not sure what to do. There is an excel spreadsheet available for water injections which outputs enthalpy, but I could not find one for CO2.
