The liquid and vapour phases are setup using two different materials created with rgp tables made using the sustemcoupling and refprop. The simulation runs and the flow field seems realistic, though a weired error message is showing up from the initialization stage itself. Please see the images attached. I am using 8 processors and this error appears eight times at cell number 0. But I have checked the total enthalpy and it seems enthalpy of gaseous phase is always greater than that of liquid phase. Then how come latent heat become negative?<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/10\/31-10-2022-1667188870-1.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/10\/31-10-2022-1667188881-2.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/10\/31-10-2022-1667188896-3.png\" alt=\"\"><\/p>\n<p>In time, printig this error message is getting slower and it slows down the entire simulation.
