zhou Guest Posts: n/a	I defined a UDS (user defined scalar). When i set boundray condition for this UDS at wall, i found there are two options: one is "specified value", another is "specified flux". My quesion is what is definition for this "specified flux". Does it means the gradient of this UDS like d(UDS)/dx or something else? Thanks.
