      When using UDS, the scalar value set at the boundary is usually transported according to the obtained flow field. Conversely, if you want to set a scalar value at the outlet and want to transport the scalar value backward from the outlet as a reverse tracer, there is a way to set it to return a negative flux as a convection term. However, since the default function cannot be used, processing will be performed using DEFINE_UDS_FLUX. Please refer to the attached document.
