Conformal PEC

This guide will cover rfx’s conformal PEC implementation:

  • Dey-Mittra method — SDF-based area-fraction weights on cut cells
  • Stability clampingconformal_min_weight parameter for CFL safety
  • Activation — single-flag sim.run(conformal_pec=True)
  • Compatibility — works with subpixel smoothing and gradient-based optimisation

See the Changelog for the v1.1.0 release notes where this feature was introduced.
