Abstract: The wheel chock handling unit includes a base, an articulated cantilever arm assembly, a main spring assembly and a force-compensation mechanism. The arm assembly has a first end pivotally mounted to the base for angular displacement of the arm assembly in a substantially vertical plane between a storage position and an extended position. It also has a second end receiving a wheel chock. The main spring assembly extends between the arm assembly and the base. The force-compensation mechanism includes a lever pivotally mounted to the base for angular displacement in a plane that is substantially parallel to that of the arm assembly.

Abstract: A method can include providing a mesh of a geologic environment that includes conformable sequences and an unconformity; interpolating an implicit function defined with respect to the mesh to provide values for the implicit function; and identifying an iso-surface based on a portion of the values where the iso-surface represents the unconformity as residing between two of the conformable sequences. Various other apparatuses, systems, methods, etc., are also disclosed.

Abstract: A method can include providing, in a geological domain, a conformal mesh, conformal to geological discontinuities of a geological model, that includes depositional domain coordinates associated with a depositional domain; providing, in the depositional domain, an initial, at least vertically structured, multidimensional grid that includes initial nodes that define grid cells; referencing the conformal mesh to identify a set of grid cells of the initial grid traversed by the geological discontinuities; splitting each of the grid cells in the set to form sub cells, each of the sub cells defined at least in part by one or more new nodes; and assigning geological domain coordinates associated with the geological domain to at least the new nodes to generate a final grid that includes the initial nodes, the new nodes and geological domain coordinates associated with the geological domain. Various other apparatuses, systems, methods, etc., are also disclosed.
