Dear all,

I am trying to impose the following boundary condition on a created UDS:

grad(UDS) = constant

could anyone help me on how to impose this boundary condition?

is it something doable directly on fluent or do I need to write a UDF for this?

thank you

isn't it same as flux = const?
it is doable directly in fluent GUI, open your boundary -> USD tab -> flux
