From searching forum I got feeling that this is impossible(UDF Adjust to redefine UDS Diffusivity ), but just in case situation somehow changed I would like to ask:
1. Is there possibility to solve the equation for UDS with zero diffusivity?
2. Is there possibility to solve the equation for UDS with zero diffusivity
in one direction?
