Hello Jean, Thank you for the reply, the procedure is definitely useful for my case. But, I have a follow up question, this procedure allow us to access the coordinates of the vertices through a CellAccessor. And before incrementing the the coordinates by a calculated value(i.e.* vertex_displacement)*, it checks if the *vertex is touched or not, *to avoid repeated increments.
I was wondering if there is any method to sequentially access all the vertex co-ordinates(Point<dim>), similar to tria.get_vertices(). The reason behind this is, let say, if I need to modify a vertex_index=10, then I need to loop over all the cells through a CellAccessor, until I hit a cell that contains this vertex and then modify it. And this could be inefficient, and I am just curious about any alternate procedures.
