Tier 2 - Unit Shape and Form


Unit Shape

  • Convexity
  • Planar
  • Concavity

Unit Form

  • Mound - High residual topography, generally convex streamwise and transverse.
  • Mound Transition - High residual topography transitioning to plane
  • Saddle - Generally convex in the streamwise direction but planar transverse to stream. The user can choose to not include this form.
  • Wall - High residal topography that is steep and planar
  • Plane - Flat (i.e., neither convex nor concave)
  • Trough - Generally concave transverse but planar in the streamwise direction.
  • Bowl Transition - Concave streamwise and transverse but relatively shallower and transitioning to trough
  • Bowl - Low residual topography Concave transverse and streamwise
