SubscriberDear Altruits, I wanted to define dynamic mesh with Six Dof in solid and interface between solid and fluid. I wanted rotate solid with a constant speed and interface of solid and fluid. Do can I define interface motion if I want that interface rotate as same speed with solid. Do you I have to define shallow wall as well? Thank you so much!

Forum ModeratorWhat's actually moving? If the motion is fixed and linear (or rotational) such that you're not changing the mesh (cell) shape sliding mesh may also be suitable.Â

SubscriberHello Rob,Â
Thanks for your reply. I wanted to rotate solid body and interface between solid and fluid with the same rotational speed. When I setup the interface, I get one interface and one shadow interface. if I want to rotate interface do I have to rorate the shadow interface as well? How can I define the interface rotating as the same speed as solid body? DO I have to use relative motion with speed "0" to assign as interface is rotating with solid body? Thanks in advance !

Forum ModeratorThe interface is to allow fluid to pass, if you have a wall & shadow pair it's not an interface. You then set motion on the fluid zone(s).Â

SubscriberHello Rob,Â
Thank you so much for your reply. I actually wanted to rotate the solid body and fluid body with the same rotational speed. Therefore, I created mesh interface in the solid-fluid wall that shares the same boundary. I considered following dynamic zones: tool:rigid with 6DOF, Fluid domain: deforming, interface 1: relative motion with respect to tool 0 and interface 2: relative motion with respect to tool 0. Would you please let me know if my dynamic mesh defination is correct? Thank you so much.Â

Forum ModeratorWhich pair are you talking about? If the two cylinders rotate at the same speed I'd use a conformal mesh.Â
