On the other hand, it should not be too difficult to implement that
yourself if you use the former functions. You only need to integrate x
over the whole domain and divide by the area of the whole domain which
you can do by taking the sum of the barycenter of each cell mutlplied by
its measure and divide by the sum of the measures. Alternatively,
integrate x over the whale domain and divide by the integral of 1 over
the whole domain.
Yes, this would work. A better starting point would be
GridTools::volume() which computes an integral that, with minor
modifications of the integrand would also yield the barycenter and, with
another small modification, the barycenter of a subdomain.
Vachan: If you'd like to implement such a function, it would be great to
have that integrated into namespace GridTools!
Best
