Hello! I am kinda stuck at the moment.

I am interested to specify point displacement field on the boundary than velocity using "motionU" as in icoStructfoam. As an beginner of OpenFoam and due to the documentation, I am asking for help in how to solve this.

Given mesh, patchID of the boundary that is moving, the displacement vector field dispVal at given time. What class should i use, what dictionary terms/solvers is recommendable?

I have noticed in the UML there is different meshmotion solvers, and a numerous applications using these, but i am little unsure which one is optimal for using icoFoam as a base class and i want to avoid use snippet coding.

What i am looking for is the required inputs to the solver, ie definition of variables, the files to be added in the case, ie dictionary stuff. Finally, i would appriciate alot for a pseudocode implementation.

From this point i can continue on my own. Thank you!
