Hi all,
I want to implement a spring-fixed model that then couples a given motion, such as a fixed stiffness rigid body that specifies a displacement over a specific time range. Displacements are discrete data, and a function can also be fitted. The spring model can be implemented in sixDof by defining the boundary type in the pointDisplacement file as follows

type            sixDoFRigidBodyDisplacement;

But the problem is to specify a displacement on a specific time scale, and the method I came up with is also to implement custom boundary conditions in the pointDisplacement file like

type            codedFixedValue;

In this way, separate definitions can be realized, and superimposed together will be contradictory. Does anyone have any experience with this, and are there other implementations available? Thank you very much.
