    Abstract: A computer-implemented method for simulating fluid flow using a lattice Boltzmann (LB) approach and for solving scalar transport equations is described herein. In addition to the lattice Boltzmann functions for fluid flow, a second set of distribution functions is introduced for transport scalars.

    Abstract: Modal dynamic analysis for finite element models (FEMs) that include Lagrange multipliers may generate incorrect stress and reaction forces. Computer systems and computer-implemented methods are provided for modifying the modal analysis to correctly generate stress and reaction forces. The systems and methods perform the modal analysis by employing a FEM and modeling stress and reaction forces of the FEM using Lagrange multipliers. The systems and methods calculate a correction term that comprises corrected values of the Lagrange multipliers. The methods and systems modify (and improve) the modal analysis by using the correction term to correct the Lagrange multipliers of the FEM, which enables the modal analysis to generate correct stress and reaction forces.

    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: The present invention relates to a method and system for performing a finite element simulation. Embodiments of the present invention determine accurate contact simulations. A method according to the principles of the present invention begins by obtaining a first finite element model and a first computer aided design (CAD) model that the first finite element model represents. Next, a finite element simulation is performed using at least the first finite element model and the first CAD model. According to an embodiment of the present invention, performing the finite element simulation comprises determining one or more variations between the first finite element model and the first CAD model.

    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.

    Abstract: A computer-implemented method includes defining respective positions of a first set of nodes and a second set of nodes in an enrichment region, and performing a coupled pore fluid diffusion and stress analysis on the enrichment region at the first set of nodes. It is then determined whether the second set of nodes is activated—representing a fracture—as a result of the analysis, and the results are visually output to a user.
