Abstract: Unlike existing methods that rely on a manual procedure for setting conditions for performing computer-based simulations, embodiments automatically set conditions for a simulation of a real-world object represented by a computer aided design (CAD) model. In one such embodiment, the morphology of a CAD mode is analyzed to identify a function of an element of the CAD model. In turn, conditions for a simulation are defined based upon one or more rules corresponding to the identified function of the element of the CAD model, where said defining includes automatically setting conditions in a simulation of the real-world physical object.

Abstract: Unlike existing methods that rely on manual procedures for repairing finite element meshes in computer-based simulations, embodiments automatically repair finite element meshes for use in simulations of real-world objects. One such embodiment begins by identifying a non-compliant mesh element in a finite element mesh and extracting a mesh patch from the finite element mesh that includes the identified non-compliant mesh element. To continue, an invariant patch description for the extracted mesh patch is generated and a repair solution corresponding to the generated invariant patch description is obtained from a database storing pre-determined repair solutions. In turn, the mesh patch in the finite element mesh is repaired using the obtained repair solution.

Abstract: Embodiments of the present invention provide an augmented reality by defining a model representing a real-world system. After defining the model, a plurality of model simulations are performed using the defined model which produce predicted field data that is stored in memory. In turn, data from one or more sensors in the real-world system is received and the defined model is calibrated using the received field data relative to the stored predicted field data. Then, an augmented reality of the real-world system is provided using the calibrated model.

Abstract: An embodiment provides a virtual reality experience by defining a model representing an object that includes experimental parameters. After defining the model, a model simulation is performed, using variations of the experimental parameters, that produces results for each of the one or more variations. The results include a value for a behavior of interest of the model for each of the variations. Next, the results are compressed to an interpolant comprising discrete polytope bins with continuous surrogates of the behavior of interest. Responsive to user provided values of the experimental parameters, a value of the behavior of interest is predicted using the interpolant. In turn, a virtual reality experience is provided by displaying to the user an effect on the model for the user-provided values of the one or more experimental parameters where the displayed effect on the model reflects the predicted value for the behavior of interest.

Abstract: A computer-implemented method for touch input via a multi-touch surface includes displaying an input widget via the multi-touch surface, wherein the input widget includes at least one control field and at least one element bar. A finger contact is detected along the multi-touch surface and substantially within the control field or the element bar. In response to detecting the finger contact, the contents of the element bar are adjusted.
