hi
i want rotate and oscillate stirrer with this equation by sliding mesh: Vteta= C*sin(teta); C is constant how can apply this type of rotation on subdomain? stirrer is in a subdomain like picture. in past i rotate it with presented cel x=(x-Total Mesh Displacement X)*cos(2*pi/D*t)+(y-Total Mesh Displacement Y)*sin(2*pi/D*t) y=-(x-Total Mesh Displacement X)*sin(2*pi/D*t)+(y-Total Mesh Displacement Y)*cos(2*pi/D*t) but it has no accelerate or oscillate. |

I don't fully understand your question, but if the motion is purely rotational then consider using rotating frames of reference.
If you are using moving mesh then this sounds like just a rotation transform which you can find easily on the web. |
