Hello Community, I am facing a problem with defining the boundary condition for a problem with help of remote displacement.
In the image attached above these wedges are rigid. I basically want to bring the radially down decreasing the center diameter from 35 to 15 in first step. In second step, at the same radial position i want to rotate the wedges about the center of circle by 180 degrees.

Hi Abhinav,

I think remote displacement is not appropriate. You can define a cylindrical coordinate system in the centre and use Displacement to apply the constraint in the radial direction and tangenetial direction. In tangential direction, it would be arc length (S=r*theta). This will depend on radial distance of each node from center. So you may give a tabular data using X(radius) as independent variable.

I want to keep these wedges as a rigid body and if i go just with displacement it will increase my simulation run timeas i will have to keep these wedges flexible.
