parabolic velocity: simple way to implement this bondary condition?

vitorspadeto · June 10, 2014, 14:08

hello

I am newbie in openfoam I saw some posts on the subject, at first I was scared. Could someone show me how to implement the parabolic velocity profile to the input of my tube (2D)? What do I do? Thanks for attention and sorry for posting this topic again. If I can implement, I will make a pdf manual for beginners to share here.

Thank you for your attention.

I use OpenFOAM 2.3.0

Using groovyBC you can do that, check out the example on "pulsedPitzDaily".

Refer: http://openfoamwiki.net/index.php/Co...ulsedPitzDaily

Also, you can refer to the chalmer's document. By following the instruction in the document you can use the patch "parabolicVelocity". I don't know much about OF 2.3.0 version, whether this BC is available in the same. If not you can install the BC using the instructions mentioned in the document.
