In the FoamGeo module in the "Basis Geometry" tab you can set the "Basis Pore-Geometry" option to "Use Current Analytic Geometry (GAD)". This option generates the foam on the basis of the curretnly loaded structure in GeoDict.
The loaded structure needs to be:
- A periodic structure
- An analytic strucutre, consisting only of GAD objects. Indicated by the green dot besides the "Objects"number in the top left corner
- Consists only of objects of sphere or ellipsoid type
So you need to generate an anisotropic ellipsoid structure on which you use FoamGeo on.
Does this answer your question? Or dou you need further explanation?
