Flux boundary condition for UDS equation

IndrajitW · December 5, 2012, 01:08

Hi all,
I am using the User defined scalar equation in Fluent and I wish to use the flux boundary condition with UDF to define the flux. However by default fluent takes the flux normal to the boundary while my flux is coming in at an angle. Please help me as to how can write the UDF for this??

Anybody who has worked with UDS??? Please help....

Hi

I think you can add some oblique pipes to realize the angled UDS boundary condition.

Thank you for your reply but Actually I wish to give a oblique flux on the wall and hence cannot add any pipes since that would change the geometry.Please suggest any other wa yto do it!!!
