combining mapped & codedFixedValue for inlet?

canopus · May 24, 2015, 06:39

Hello
Is it possible to combine the mapped inlet with a codedFixedValue in OF?

The purpose is that I want to put an oscillating flow and map it back at downstream
so that I can get a developed profile without using a long channel segment?

Thanks
SM

Just to further clarify the problem

I want to do LES of an oscillating flow i.e. a sinusoidal flow without a mean component in a channel.
In order to have a fully developed flow at lower mesh count without using a long channel I want to map it back at a location from downstream or recycle from outlet.

For sinusoidal profile I used codedFixedValue in RANS.
For mapping I can use something like mappedpatch as in PitzDailyMapped tutorial.

Is it possible to combine the mapped inlet with codedFixedValue in some way?

Any other suggestions which reduce computational effort are also welcome .

Hi,

Have you found a solution? I'm working on a similar project
