Hi, I have a data file from an AMR simulation stored as an unstructured Hexahedron mesh xdmf + h5 files. When I do streamline tracing, the streamline terminates at boundaries of different zones with different resolutions (see my attachment; in this case my data is polar).
To trace streamline across such boundaries
- Is it possible to connect these zones?
- Do I need to convert the data into a Paraview-compatible format? What do I need to know and do?
- The last resort in my head would be to resample onto a regular mesh, hopefully, polar/spherical. I haven’t started learning about that yet, any suggestions?
Any suggestion is appreciated.

The xdmf is like
