Abstract: Editing features of a history-based computer-aided design (CAD) model may be difficult and may require redesigning much of the CAD model modify features. The solutions described herein allow a design engineer to modify an existing history-based CAD model by automatically determining history-based features that need to be converted to direct-edit features, creating a body of direct-edit features from the determined features, and creating a model containing both the direct-edit feature body and remaining history-based features. Such a CAD model containing both kinds of features may be referred to as a hybrid model.

Abstract: A computer method, apparatus and system simulate hydraulic fracturing. The computer system/method models a wellbore of an injection well. The wellbore model includes a hydraulic drill pipe element in a borehole and related fluid flow in the borehole. The borehole workflow is modeled in a subject rock formation. A simulator operatively coupled to the model obtains pressure values from the modeled borehole workflow and modeled wellbore. The simulator automatically converts pore pressure from the modeled borehole into a mechanical pressure load on the subject rock formation. The mechanical pressure as hydrostatic pressure is automatically applied to the surface of the rock formation affected by the borehole and responsively defines one or more pressure induced fractures. A 2D or 3D graphical representation of the pressure induced fractures in the rock formation are displayed on output.

Abstract: An embodiment of the invention involves increasing the penalty stiffness within a finite element simulation increment, which is more accurate because it avoids following a solution path with significant non-physical penetrations. An embodiment of the present invention begins by determining a first value of a parameter used by a finite element simulation of a load increment. Next, a first solution of the finite element simulation is determined by performing Newton iterations using the first value of the parameter until a first convergence check is satisfied. Then, a second value the parameter is determined wherein the second value of the parameter is unequal to the first value of the parameter. Finally, a second solution of the finite element simulation is determined by continuing the Newton iterations using the second value of the parameter until a second convergence check is satisfied, the first convergence check being different than the second convergence check.

Abstract: A computer based scheduling and rescheduling method, apparatus and system for an electronic calendar. The electronic calendar illustrates a time progression of scheduled tasks in a horizontally or vertically oriented view of time. The electronic calendar and its graphical user interface (GUI) provide a viewing pattern for the user. Direction in the viewing pattern is synonymous with increasing/decreasing dates-times in the time progression of scheduled tasks. A scheduling-rescheduling engine schedules into the calendar user requested tasks and automatically reschedules impacted previously scheduled tasks. The scheduling-rescheduling engine also schedules user selected resources (e.g., people, robots, tools, etc.) per scheduled task.

Abstract: Computer simulation generates improved 3D images of human movement involving an object associated with the human character. A set of axes in 3 dimensional space is originally defined for tracking orientation of the human character in a 3D image. This set of axes is subsequently automatically applied to and used for object(s) carried by the human character. The object is displayed at a constant (same, unchanged) orientation while the human character is illustrated moving in certain ways in succeeding 3D images.

The apparatus includes a graphical user interface (GUI) which includes a visual depiction of the 3D model as well as a cursor and 3D animated icons which are representative of various transformations that may be performed on the model.

The method includes displaying, on a GUI, a 3D model as well as a cursor and at least one 3D animated icon which displays a representation of a respective transformation. The method further includes changing the state of an animated icon from static (i.e., a still frame) to animated when the user positions the cursor in the neighborhood of the icon, thereby illustrating the effect of the transformation.
