Acknowledgements

ORION is built upon several open-source projects and commercial products.

Lib_VTK_IO

VTK I/O Library for Fortran

Lib_VTK_IO delivered robust, well-tested routines for handling VTK structured and unstructured data formats. ORION extends and adapts these capabilities to fit into a unified multi-format framework.

Key contributors to Lib_VTK_IO: - Víctor Sande - And the broader Lib_VTK_IO community

OFF (Open source Finite volume Fluid dynamics code)

Tecplot Format Handling

  • Repository: github.com/szaghi/OFF
  • License: GPL v3.0
  • Contribution: Provided basic Tecplot format reading and writing routines

OFF's Tecplot handling routines formed the basis for ORION's Tecplot ASCII support. The clean, modular design of OFF made it an excellent starting point for building ORION's format abstraction layer.

Key contributors to OFF: - Stefano Zaghi - And the OFF development team

TecIO Library

Tecplot Binary Format Support

  • Provider: Tecplot, Inc.
  • Purpose: Reading and writing Tecplot binary formats (.plt, .szplt)
  • License: Tecplot License Agreement

TecIO enables ORION to work with high-performance binary Tecplot formats, essential for large-scale CFD workflows.
