INC_INLET_USENORMAL - velocity direction @ inlet

gbettega · April 5, 2024, 02:34

Hello
I have to handle multiple inlets in a fluid domain
I would like to inject flow along a user-defined direction for some inlets, and along a local, auto-computed direction for other inlets.

The solver setting

INC_INLET_USENORMAL= NO

(or YES) it's what I need.
Does this setting affects ALL the inlets at one time, or is it possible possibility to define a list of bool values, for assigning Y/N to the list of inlets (e.g. INC_INLET_USENORMAL= NO, YES for inlet1, and inlet2)

Grazie mille

At the moment INC_INLET_USENORMAL takes one single value for all inlets.If you would like to see this functionality, you could add a feature request on github (or implement it yourself). I think it is a good idea to add it.

Thank you
I expected a situation like that.
Actually it's a minor, I think, change, but could be important. Tools like Ansys CFX usually give the possibility ti apply such a setting to all the user defined onlets. My answer comes from a long activity whose result is a GUI integrated environment, meshing and post included, able to handle flow simulations, using Su2 as a solver, so, in setting "inlet options" I encountered this issue (which actually Is not a true issue).
Grazie mille
