Hi Maria, You can also use kuibit, which knows how to read the various files and combine them.
Assuming `sim` is your SimDir, `sim.gridfunctions.xyz` is a dictionary-like object that contains all the grid functions in those files. For instance, `sim.gridfunctions.xyz["rho"][0]` is going to be a `HierarchicalGridData` for your 3D rest mass density at iteration 0. This data structure contains all the information for the various refinement levels in the data. You can resample it to `UniformGridData` for visualization purposes. Processing large 3D data with kuibit can be computationally intensive.
