GRID OPTIONS

The unstructured Cartesian grid in RotCFD is capable of dynamically refining the grid to adapt to flow features, such as vorticity.

  • Structured Cartesian
  • Unstructured Cartesian with body-fitting
  • Viscous grids


GRID ADAPTATION

The unstructured Cartesian grid in RotCFD is capable of dynamic localized refinement to adapt to flow features, such as vorticity.


GROUND EFFECT

Rotorcraft in ground effect incur complex aerodynamics and can cause a significant amount of shear stress on the ground.


DUST MODELING BROWNOUT

The shear stress on the ground caused by rotorcraft can result in the entrainment of dust particles, potentially leading to brownout conditions. RotCFD is able to model the dust density of rotorcraft in ground effect.


AEROACOUSTIC ANALYSIS

RotCFD has been coupled with an aeroacoustic analysis module. This module uses the RotCFD rotor solution as input to calculate the sound pressure levels at various points in the flow field.
