PreProcessing | Airfoils and Wings | Structured Mesher | Quad-Hex

Construct2D is an open source preprocessor for building the computational structured grids around wing sections. It may also work for other shapes though. Basically it works on 2D but also has a limited 3D capability by extruding the 3D grid on z axis.

The software has no GUI and written in Fortran. Indeed it does not need a GUI and works perfectly and efficiently via the command line.

The input file format used by Construct2D is the same as that used by XFoil. It is recommended that input airfoils have a chord length 1 and a leading edge at x = 0.0. When the grid generated, a script can be run for visualization and inspection of the grid.

Features of Construct2D

  • 2D computational structured grid generation
  • 3D grid capability (Only for extruding the 2D mesh on z axis)
  • Hyperbolic grid generation for fast and high quality solution
  • Elliptic grid generation when required
  • C and O grid topology
  • Easy and standard geometry input
  • Working with both sharp and blunt trailing edges
  • Wall yPlus control
  • Grid visualisation, inspection and quality control capabilities
  • A perfect companion for OpenFOAM
