GridGeo

Generating Lattices in 2D and 3D

Regular structures in the 2D-plane or in 3D space can be generated with GridGeo. In combination with other GeoDict modules, a wide range of application is possible, like e.g. structures for flow and filtration simulations, mechanical simulations, or benchmarking structures.

Topics of GridGeo

  • GridGeo Section
    Access the available GridGeo sub modules via the GridGeo section.
  • Grid of Spheres
    Create the four common sphere lattices: the Simple Cubic, Body-Centered Cubic, Face-Centered Cubic and Hexagonal grids.
  • Grid of Parallel Cylinders
    Parallel cylinders are arranged in the plane.
  • User Defined Grid
    This is the most powerful option in GridGeo. Periodic arrangements of an arbitrary selection of objects can be generated in 3D, even with non-orthogonal basis vectors.
  • Perforated Foil
    The Perforated Foils are flat membrane-like structures with differently shaped holes that conform to the specified perforation parameters.
  • Grid GeoApps
    Selection of predefined macros which create specific regular structures. The macros can be found in the installation folder.
