Processing Tools for Verifying the Yang Pressure Boundary Condition in HemeLB

This release provides the preprocessing and postprocessing scripts used to verify the Yang pressure boundary condition implemented in HemeLB. The scripts are designed to support the preparation and analysis of simulations of Poiseuille flow in cylindrical pipe domains, which are derived from a common cylinder geometry but differ in orientation: one aligned with the computational grid and the other rotated by 20 degrees to introduce grid misalignment. These tools facilitate input generation and postprocessing across a range of spatial resolutions, enabling evaluation of the Yang pressure boundary condition’s performance under different geometric and discretisation scenarios.
