Hello Foamers,

I want to ask if there is a way i can code a cylinderTocell field to oscillate.
Indeed, I created cylinderTocell field using topoSetDict, I want to know it can be put in motion.
I have seen in interFoam tutorials, setFieldsDict is used to give a velocity to a boxtocell Field.

Please help me to find out if there is a way this cylinderTocell Field can be moved(oscillating motion).

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?

I will be happy to hear from you.


Regards!

I think if you convect the field F by solving


fvm::ddt(F)
+ fvm::div(phi, F) = 0


it should work.


In principle you should solve a 3D advection equation. The mass flow
phi = fvc::interpolate(U) & mesh.Sf();

U has to be modified each time step to the desired value.

Hello,
Thank you for reply,
Help me as a beginner of Open Foam, How to model and code such oscillating motion of the Cylinder Field. Which solver to modify and which tutorial should I consult to understand this.

I have attached on this post my case setup that have lead me to that cylindrical shape.

Hope you are going to help

Thank you!
