GadGeo

Construct and manipulate material models

GadGeo allows to construct 3D geometries from basic 3D objects like spheres, ellipsoids, fibers, etc.

The module also contains all functions available to manipulate these 3D objects in GeoDict. You can create a 3D structure in one of the other structure generation modules of GeoDict (e.g. FiberGeo or GrainGeo) and then modify this structure in GadGeo. You may remove objects from the structure or add new objects to it. You may change the properties of any object in the structure (size, position, Material ID).

You can change the field of view or the resolution of the domain with GadGeo, too.

The Export as GAD Objects command does not directly export visualized results like particles, trajectories and streamlines anymore. Instead, you can use the new Convert to GAD commands to convert the visualized results to GAD objects first, and then export the 3D structure.

Learn to use GadGeo:
Introduction to GAD Objects Learn to distuiguish between geometric object descriptions and their representation in a 3D voxel mesh. Object Types Find descriptions and parameter lists of all available object types here. Create / Add GAD-Objects Create new objects or add objects to the current structure. Edit GAD Objects Modify the current objects in various ways. Edit Domain Change the domain settings. Create GAD Index Image Access the object index numbers. Create GOF Orientation Image Make the intrinsic orientation of the GAD objects available for subsequent simulations. Add & Import Import GAD objects from a file and add them into the current structure or domain. Export as GAD Objects Create a GAD file from the current objects. Convert to GAD Convert visualized results like particle trajectories or streamlines into GAD objects that become part of the 3D voxel structure. Algorithms Modify the existing objects through a collection of algorithms.
