Dear Foamers,

I am performing some 2D simulations with fluctuating flow in a channel with an obstacle inside. What I do is having a fixed domain (the channel flow with the obstacle attached on the lower wall) with a timeVaryingUniformFixedValueBC at the inlet & outlet for the velocity. So far I performed my analyses using pimpleFoam and turbFoam.

Now I want to do something different. I don't want to use a fluctuating flow anymore as BC but I want to move the whole domain with a fluctuating velocity (same as flow velocity). Please note I don't want any deformation of the mesh.


Questions are:

which solver is optimal for this application?

Which boundary condition is required to simulate the motion of the whole domain?

Is there any example available which is similar to what I need?


Looking forward to your feedback,
Alessio
