      How can I find total pressure? I need to get a mole fraction of species in UDF and calculate it by dividing partial pressure by total pressure. Does C_P(cell, thread) + p_op give total pressure or not?

      If it's a gas isn't mole fraction the same as volume fraction? Given we also know the cell volume and mass you can use that route too. Remember in CFD we know a lot more than you might in an experiment, and in a more accessible form.
