Hi all, I am solving a problem where one of the functions in the assembly process requires the knowledge of the boundary coordinate of the mesh, which moves at each timestep.
My solution should be only varying in the y-direction (it is indeed with the current output) and I have a known linear function independent of x so I only need the y coordinate of the top boundary above the relevant x-y coordinate at each assembly. (I basically need the hydrostatic pressure function that is dependent on the depth only). ie. I need to calculate p = 1.5*(top-boundary-coordinate directly above the actually coordinate - coordinate in question) + 1 for each cell vertex in the assembly. I've tried looking a cell->face(face_no)->at_boundary() type input within the cell iterator and by using something like cell->vertex(v)(1) but I can't quite get my head around how to find the y coordinate of the top boundary for every cell/quadrature point calculation. I'd appreciate any help.
