Abstract: Disclosed are techniques for scalar solvers in flow simulations that include simulating using a scalar lattice velocity set in a computing system, movement of scalar particles representing a scalar quantity in a volume of fluid, with the scalar particles carried by flow particles of the volume of fluid, and with the movement of the scalar particles causing collisions among the scalar particles; and evaluating, a non-equilibrium post-collide scalar distribution function of a specified order that is representative of the scalar collision.

Abstract: Embodiments determine acoustic impedance of liners. An embodiment defines a three-dimensional (3D) computer-based model of a liner and performs a digital experiment of the liner in an environment using the defined model. Results of performing the digital experiment include a reference transfer function. A two-dimensional (2D) model of the environment is generated where the liner is represented by an acoustic impedance boundary condition with an impedance value defined by a resistance value, reactance value, and non-linear coefficient. Iteratively, the impedance value is modified and a 2D simulation is performed using the generated 2D model of the environment with the acoustic impedance boundary condition with the modified impedance value, until a transfer function resulting from performing the 2D simulation matches the reference transfer function. The modified impedance value used in performing the 2D simulation resulting in the transfer function matching the reference transfer function is acoustic impedance of the liner.

Abstract: Embodiments calculate birefringence of materials. One such embodiment builds one or more three-dimensional structure models of one or more compounds forming a material. Each built three-dimensional structure model is aligned along a molecular axis and one or more tilt angles are set for each aligned three-dimensional structure model. A molecular polarizability tensor for each three-dimensional structure model with the set tilt angles is then calculated. An embodiment accounts for anisotropy by measuring the width and length of each model with the set tilt angles to determine aspect ratios. To continue, birefringence of the material is calculated based on the determined molecular polarizability tensors of the one or more models. Embodiments can be employed for simulating, optimizing, and designing real-world objects, e.g., in an optimization to select a material for a phone display that conforms with performance/manufacturing requirements.

Abstract: A method for validating a query result for a query of a database uses an index of the database. A selection of a set of source data from the database is received and a first hash operation is performed on the source data in the database resulting in a database hash value for the source data. A second hash operation is performed on the source data in the index resulting in an index hash value. The index hash value is compared with the database hash value, and a guarantee indication is provided for the source data in the index.

Abstract: Grasping remains a complex topic for simulation. Embodiments provide a method to automatically determine grasping cues for tools. An example embodiment scans a CAD model representing a real-world tool to generate a series of sections from the CAD model. In turn, properties of each section are extracted and one or more regions of the CAD model are identified based upon the extracted properties and a tool family to which the tool represented by the CAD model belongs. To continue, a respective classification for each of the one or more identified regions is identified and grasping cues for the CAD model are generated based upon the determined respective classification for each of the one or more regions.

Abstract: Embodiments are directed to computer systems and methods that provide a data-driven approach to product benchmarking. The systems and methods identify a product being developed on a product development platform. The systems and methods repeatedly evaluate products similar in operation to the identified product. In response to the evaluation, the systems and methods automatically determine current performance capabilities of the similar products and digitize the determined current performance capabilities as current benchmark parameters in a central database integrated within the platform. The systems and methods generate output, by an application of the platform, based on searching the current benchmark parameters in the database, and develop functions and parts for the identified product using the generated output. For example, the systems and methods may invoke a modeling application of the platform to automatically determine a part for the identified product by performing a simulation using the searched current benchmark parameters.

Abstract: Embodiments determine positioning of a mannequin. One such embodiment begins by determining a frame of a grasping element of a mannequin represented by a computer-aided design (CAD) model and determining a frame of an object to be grasped, where is object is also represented by a CAD model. To continue, degrees of freedom of the mannequin are specified and limits on the specified degrees of freedom are set. In turn, using an inverse kinematic solver, positioning of the mannequin grasping the object is determined based upon: (i) the determined frame of the grasping element, (ii) the determined frame of the object, (iii) the specified degrees of freedom, and (iv) the set limits on the specified degrees of freedom.

Abstract: A computer-implemented method is disclosed that includes receiving content associated with a heap dump of a computer application, generating a plurality of files based on the heap dump content, and loading the files into the graph database. The files so generated are compatible with the graph database. In some implementations, additional analysis and route finding (e.g., finding the relationship between two nodes) may be performed on the resulting object graph.
