I am using FEATool to get a simulation of a FSI - Fluid Structure Interaction. My first subdomain is suppose to be a sphere - the solid. My second subdomain is an air stream/jet/inlet - the fluid part.
With the inlet my sphere is supposed to move in the stream/geometry, that does work.
Now my question is, if its possible to get an interaction between my sphere and the walls of the air stream? (its set up as Wall/No Slip) in the boundaries, because right now the sphere will move out this geometry/stream with no collision at the walls of the jet.
I am working on a simulation of FSI (Fluid Structure Interaction) similar to yours – the motion of a solid sphere in a flow domain. However, my sphere is not move in the stream successfully.
I set the boundary condition of the sphere as “Fluid-Structure interface”. Then I call the “FSI Solver”. An Error message pops up that is “No boundary conditions are imposed on component 1”. I promise I have set. Does it require additional boundary conditions?
I have no idea how to solve this problem. Sincerely request any advice and suggestions.
