SubscriberHello dear expert,
I am going to model a moving rigid vortex generator that moves adjacent to the top wall of a backward-facing step.
Starting with a simple simulation, I want to model a rectangular fin.
I am using ANSYS Fluent to solve the fluid domain. When I draw the geometry, I make two parts, one solid and a fluid.

Forum ModeratorIs it moving along the wall (eg a scraper) or vibrating (ie bending in the flow)?

It is moving along the wall with a given sinusoidal velocity.

Forum ModeratorOK, so a scraper. I'd use layering and non-conformal interface zones. You may need to model the wall as a solid if it need a thickness.

SubscriberThanks for your answer.
I have surfed the net to understand how to define non-conformal interface zones, but it seems to be practical for two or more adjacent zones that are meshed separately, so we should define their interface boundaries as non-conformal. However, In my case, the solid part is a rigid body and does not require to have any mesh. What should I do in this case?

Forum ModeratorYou may need to rethink the meshing approach to define the shape and then allow it to move. Most modelling needs some planning to set up the geometry & mesh to then use the solver tools.

SubscriberThanks for your guidance. I will reconsider the whole approach.
