I solved the finite element task for the elasticity problem and obtained

need the function that returns the stress tensor for a given point.
How to find the cell in which given point lies?
You will want to use something like the VectorTools::point_gradient() function
for what you want to do. You should take a look at its implementation to see
how it works and how it finds a cell.
