Abstract: Embodiments determine wear. One such embodiment obtains, in memory associated with a processor, a finite element mesh representing a first object. For a given node of the obtained mesh, a wear variable is associated and linked to contact constraints associated with the node. A simulation of contact is performed, over movement increments, between the first object and a second object to determine wear at the node. Wear distance is iteratively determined for a given increment using the mesh, the associated variable, and the constraints. A position of the node in the mesh is iteratively updated based on the determined wear distance for the given increment, until the wear distance for each of the increments is determined. The wear at the node is determined based on the determined wear distance for each of the increments. An indication of the determined wear is output.
