but during compilation I get the following error:

The function wants a pointer to a free function, but you pass a pointer
to a member function as argument. You have two options:
* If you can, make the member function `static` so that it doesn't need
an object to work on any more.
* Create a bound member function pointer using
boost::bind (&Step15::MinimalSurfaceProblem<dim>
::rescale_body_length,
this,
std_cxx11::_1)
or (if your compiler supports C++11), using a lambda function:
[&this](const Point<dim> &p) -> Point<dim>
{ return this->rescale_body_length(p); }
Best
