Hi Shamkal:

The corrosion tool is new and does not support the multiphase framework.  So far, simulations are restricted to single phase.  Probably the error occurred because water was not found in the gas phase mixture where it is expected.

I would try entering the tool with a single phase mixture containing water-liquid and CO2. The only difference is that "liquid" and gas phase species will share the same velocity and temperature fields.

Best Regards,
