I thank you Yage,

Though the exercise is still not working for me but at least you have been with me.

now when i add this in my blockMeshDict:

solid
{
type wall;
faces ();
}
and run the blockMesh it brings errors of:

-> FOAM FATAL IO ERROR:
keyword faces is undefined in dictionary ".solid"

file: .solid at line 83.

From function const Foam::entry& Foam::dictionary::lookupEntry(const Foam::word&, bool, bool) const
in file db/dictionary/dictionary.C at line 441.

FOAM exiting


May you try the case for me(Find attached updated case), so that we can be done at once? instead of keeping posting.

I reduced the background to (25 10 0.1)


I will be happy for support.

Regard!

Yes, my ultimate goal is to simulate flow over that cylinder? (stationary and oscillating).
I thought that cylinder will be immersed not body fitted? Does it sound feasible?

Finally I got that cylinder in my paraview(see attached images). the problem were to not include Zones in paraview. Then is there away i can move that cylinder?(oscillating motion). which codes should i use? can mysetField dictionary help?

Say if the solid region eta=1 and fluid region =0, is there a way i can alternate eta to move that cylinder or? (eta: 0 0 0 0 1 1 1 1 1 0 0 0.....)

Just advise me how i can move that cylinder without dynamic mesh.


Thank you!
