###
Step 1: s
ampling
###
Geometry S
ampling
The generation of the fracture networks occurs by randomly sampling instances of the
desired fracture geometry on the basis of probability distribution functions, which
can be defined by the user. The implementation allows for both selecting the type of
distribution (uniform, exponential, etc.) as well as the distribution parameters.
###
Step 2: checking constraints
###
Constraints Evaluation
After the generation of a new candidate for a fracture, a number of constraints can
be evaluated for it. These can be used to enforce topological characteristics of the
fracture network, e.g. fracture spacing, by defining a minimum distance between entities.

ragmentation of the network
After the desired number of fracture entities have been generated, an __EntityNetwork__
can be constructed from the raw entities. This intersects and fragments all entities, and
if desired, one can confine the network to a domain of choice.
