AMReXplorer is a C++20 and Qt 6 desktop application for interactive visualization of AMReX data. One executable opens 2-D and 3-D plotfiles as well as standalone FAB and MultiFab data.

Highlights

• Demand-driven AMR reads with a bounded data cache
• IEEE-32 and IEEE-64 FAB input
• First-class raw MultiFab and FAB exploration, including per-dimension cell/nodal index types, ghost-cell-aware MultiFab views, multi-file FAB selection, and full stored-FAB inspection
• Composite and exact-level views, value probing, line plots, grid boxes, contours, and vector glyphs
• Three orthogonal slice views and an isometric overview for 3-D data
• 2-D spherical (r, θ) plotfiles rendered in physical R–Z, or as the logical r–θ / θ–r grid
• Plotfile-sequence and plane-sweep animation
• Multiple palettes, logarithmic and user-defined ranges, and PNG/FITS/MP4 export

Documentation

• Installation — dependencies, source builds, and packaged applications
• User Guide — workflows, controls, animation, export, shortcuts, and troubleshooting
• Developer Build Guide — CMake presets, supported compilers, and validation

The User Guide is also bundled in the application under Help > User Guide... for offline use.
