Beschreibung
Zusammenfassung:	The object of the invention is a method implemented in a computer for the numerical simulation of a porous medium that may comprise multiple interacting hydraulic fractures in continuous or naturally fractured medium. The method calculates numerically the propagation of a crack, or set of cracks, for instance under the fluid pressure imposed artificially through a well or perforation in a rock mass. This is accomplished by using the Finite Element Method and the special elements named zero-thickness interface or joint elements in the specialized literature, which are pre-inserted along all potential crack paths in the rock mass (pre-existing natural and artificial fractures plus main potential new fracture paths).
