error estimate

[Lin Ji]

Hi, Christophe,
    To follow up a previous discussion on error estimate, can we ask GetDP to
provide the error estimation or the number of valid digits of the solution?
    As I understand, to increase the accuracy of solution, we can either
refine the mesh or raise the local interpolation order. So, how do we define
a higher interpolation order in GetDP? What is the default order for solving
the wave equation example you sent us?  Thanks.
