getting right unit of mass source term
 

Hi to all,Does anybody know that how can I have right unit for mass source term in udf?Now its unit is s^-1 ,Do you think that multipling it by density in order to get right unit is correct theoritically?thanks a lot in advance

Quoting the manual: "a source term for the continuity equation would have units of kg/(s m^3)." In general, your source term needs the units of the relative differential equation NOT integrated on the volume.
