The present invention relates to the determination of damage to a geological model comprising a plurality of nodes and a plurality of links each linking two nodes from the plurality of nodes. For each link from the plurality of links, the determination of damage comprises determining a force applied to said link. If the force is greater than a force threshold value, for each node of the two nodes from the plurality of nodes linked together by said link, the determination of damage comprises creating a contact sphere associated with said node, and eliminating the link. The determination of damage comprises determining a plurality of contacts between spheres comprising at least one contact between spheres, each contact between spheres associating two contact spheres from the plurality of contact spheres.

Method and device for determining damage to a geological model

The present invention relates to a method for determining a karstic region modified by karstification phenomena. This method comprises, from a geological model, determining a seed cell and a target cell in that model. If a distance between the seed cell and the target cell is above a given distance, it is possible to update the seed cell with a bifurcation cell based at least on the coordinates of the seed cell, the coordinates of the target cell, a distance distribution, an angular distribution, and to re-iterate the test. Based on that bifurcation cells, trajectory is computed and cells of that trajectory is updated with new cell characteristics.
