How to extract the particle incident angle

Augustin_MOREL · November 17, 2022, 09:37

Hello,

I'm currently simulating a flow with particles injected and I would like to
extract the incident angle of each particle. I mean the angle between the velocity vector of a particle and the wall normal.

I generated a track file, and I can see in the manager that there is "ParticleIncidentAngle", however according to Star CCM+ :

" This function is provided for use in boundary condition expressions, it is not available for visualization, reporting, or recording on the track file."

So, I don't know how to extract this data. I guess that it should be possible to create a report which will calculate this angle but I don't really how.

Do you have an idea ?

Augustin.

Did you try to get it at boundaries via Boundary Sampling?

Hello,

Thank you very much for your answer. I used that tools and it worked.

Have a nice day.
