Help Desk gao naiping writes "I do CFD simulations in the field of HVAC. At this moment, I want to simulate the distribution of one poisonous gas in a ventilated room which is evaporated from one wall at a fixed mass flux. However, if I open the equation of species, the wall boundary conditions can only be set as fixed mass fraction or zero diffusion. Could you inform me how to set the wall boundary as fixed mass flux as to the species diffusion. If using UDF, could you give me more details?

By the way, In one of my cases, a human body is placed in a room. The geometry of the human body is obtained from 3D laser scan technique and the body surface is composed by 1200 small patches. If I want to calculate S2S radiation. Will there be any problem in the calculation of view factors?

Thanks!"
