udf of flux function in the UDS equation
 
Hello there, has anyone here ever tried adding extra advection term to the convection term in the normal scalar transport equation (also called UDS equation) in ANSYS Fluent? It should be common in simulation of wind-induced snowdrift or sediment process in rivers, in which extra mass flux on the vertical direction should be considered because of gravity. I failed to write the correct UDF for the final advection term and got bad results. If you are also interested in the topic, pls let me know!

Best regards,

Weijie Zhao
