Dear Danila,
in PIConGPU before 0.2.0 it is possible to get a `gridGlobalOffset` equivalent attributes from each dataset.
Each dataset contains an attribute named `_global_start`. It defines the distance in cells from the current data to the origin (point in space at time step zero) of the simulation.
Best regards,
René

Dear all,
I have a questions regarding data save and post-processing in picongpu.
As far as I got it openPMD is currently supported by a dev version
(looks like 0.2.0 also has it). The standard defines an attribute
gridGlobalOffset which is very helpful for simulation with moving window.
I would like to ask you if there is a way how to define a
gridGlobalOffset in 0.1.2 version? Indeed, the way how HDF5 dump is
described here
<https://github.com/ComputationalRadiationPhysics/picongpu/wiki/HDF5>
doesn’t assume such kind of an attribute.
Maybe there is another way how one can deduct the coordinate of the
moving frame at given timestep?
Best regards,
Danila.
