Visualise Blend Factor of advection scheme in CFX-Post

pamstad · September 26, 2019, 10:05

Hello everybody,

I'm wondering if it is possible to visualise at which location in my domain, which value of the blend factor was used? I haven't found anything in the CFX Tutorials or Guidelines.

(Info: I'm using CFX 19.2)

Thanks a lot for your help and have a nice day!

Which advection scheme model are you using?

Sorry for the incomplete information.

I'm using the High Resolution one. According to the Ansys documentation, the blend factor varies between 0 and 1 in the domain (according to local gradient and laplace operator of distance vector r).

My Goal is now to visualise/see what values of the blend factor are used, in different parts of the domain.

Thanks a lot for your answer!

Look into variables suffixed with .Beta

That is the 0->1 coefficient the documentation is referring to

Hello opaque,

thank you for the answer, my question is answered.

As I try to get familiar with the ansys guides, I'm interested in where you have found that information in the ansys guide? Or what would be your procedure to get that information?

Thank you and have a nice day!
