The GridGeo module models periodic materials (patterns), such as regular configurations of cylinders, spheres, arbitrary objects, and drill-holes. These drill-holes are elliptical, rectangular, change diameter with depth, or have a linear or curved gradient.
The format of these geometric models is 3-dimensional images, like µCT-images after the segmentation, or an analytic description (*.gad, GeoDict analytic data).

By changing the parameters underlying the model, new material structures are designed and their material properties are computed. New designs and existing products are compared and performance is optimized.

GridGeo realistically models the 3D structure of any regular material, such as dense regular sphere packs in BCC grid (Body-Centered Cubic).
The repeating grid unit-cell might be any combination of basic objects, like spheres, cylinders, boxes and other objects. The module GridGeo also models the 3D structures of perforated foils with variable holes’ shape.

• Modelling of dense regular sphere packs like SC, BCC, FCC and HPC.
• Modelling of perforated foils.
• Modelling of (metal) gratings.
• Modelling of sand control screens.

• The GeoDict Base package is needed for basic functionality.

• The ExportGeo module can be used to export the 3D structures modelled with the GridGeo module as 3D image (*.raw), as surface triangulation (*.stl) for CAD-programs, or as direct simulation in Fluent / Abaqus.

• Selected material properties computed using other GeoDict modules for the resulting regular grids or foils 3D models are:
