Real box in Fortran

[Mephiiistopheles]

Hi all,

I've been following the Multifab tutorial and trying to recreate it using the Fortran interface. Am I missing something, or is there not currently any provision for directly creating a Real Box via the Fortran interface, such that specifying the physical dimensions of the domain is most readily done via an input file?

Many thanks in advance.

There is no RealBox in Fortran. But you can call amrex_geometry_set_prob_domain instead of using an input file to specify the physical domain size. This needs to be done before any Geometry objects are created.

Note that traditionally all amrex::Geometry objects had the same problem domain. We relaxed that constraint and now in C++ one can have different problem domains in different Geometry objects. However in Fortran, we still have all amrex_geometry objects sharing the same problem domain.

That works perfectly. Thanks a lot for your help.
