Hello, I'm doing aeraulic modelisation in operating room, I want to display relative humidity, I know that I must use species model(I read it in section 13.4) with mixture templete. In species panal-selected species there is N2,O2,H2O, but I want to have mixture with dry air and h20(vap), because in bondary conditions I may to put only the massique fraction of H2O(vap), how to do ???????????
