I have a PDE-system defined on an empty circle mesh which I get by taking the circle mesh and using the exterior boundarymesh. After getting the solution function I wish to look at the array of the solution directly, dvs u.vector().array(). But I can not figure out of these points are ordered, that is to say, what value in the array corresponds to the solutions value at a particular point in the circle. It does not seem to follow any obvious ordering to me. Could anyone please help me with this?
