Hi, I am new to the SU2. I want to perform a flow prediction with an already existed velocity profile as inlet. However, I found the inflow boundary condition only permit uniform inlet velocity.

Do you have other inlet conditions available to set specific velocity profile? Thanks a lot.

Hi,

This is a feature that we have on our list of things to implement, but we have not found the time to add it yet.

If you are interested in modifying the current code to suit your needs, you can find the current implementation of the subsonic inlet BC in void CEulerSolver::BC_Inlet(CGeometry *geometry, CSolver **solver_container, CNumerics *conv_numerics, CNumerics *visc_numerics, CConfig *config, unsigned short val_marker) within solver_direct_mean.cpp. Please feel free to contact us if you are having issues while developing the code. It would be great to include your implementation back in the master version of the code in the open source!

Cheers,
Tom

Hi,

I need to implement a velocity profile for inlet BC. I don't see this implemented in latest codes yet (on 6 November from github). Is there any development currently going on?

Hi,

This feature has been requested a number of times (so we're keeping an eye on it), but at the moment, there isn't a particular implementation underway. If this is something that you might be interested in helping to develop, please let us know. We would be happy to help!

Cheers,

I would surely like to help develop this feature. Please let me know more details regarding this.

I am also looking forward to this implementation. What is the latest news about it please?

Hi chintan,

Thanks for your interest in developing this feature! I think that it should be a fairly straightforward implementation, if you're still interested.

To get started, I would recommend forking the code on GitHub and getting familiar with the BC routines within solver_direct_mean.cpp. We essentially need to implement a way to specify either an individual state at each node or a way to read from a fit within the inlet BC.

Please feel free to contact me if you have questions,
Tom

Hi.

I want to perform a inflow problem with a velocity normal to the inlet boundary which have the curved surface.
can anyone know the way?

I know it has been requested a number of times. I am currently modelling an exit guide vane and need to use a radial total pressure and temperature distribution as well as a constant swirl angle as an inflow boundary condition.

Has this been added recently or is any current development going on? Otherwise I'll try adding it.

Best regards,
Ole

A general implementation is not yet available. But you can have a look at this branch to see how to do it on your own: https://github.com/su2code/SU2/tree/...e_inletprofile
