Abstract: A computer-implemented method of machine learning including learning a Convolutional Neural Network (CNN) architecture for estimating a degradation generated by a denoiser on a ray traced image. The method includes obtaining a dataset and learning the CNN architecture based on the obtained dataset. The learning including taking as input an image generated by the denoiser and a corresponding noisy image of the provided dataset and outputting an error map. This forms an improved solution with respect to estimating a degradation generated by a denoiser on a ray traced image.

Abstract: Techniques for simulating fluid flow using a lattice Boltzmann (LB) approach for solving scalar transport equations and solving for total energy are described. In addition to the lattice Boltzmann functions for fluid flow the techniques include modifying a set of state vectors of the particles by adding specific total energy to states of particles that will be advected and subtracting the specific total energy from states of particles that will not be advected over a time interval and performing advection of the particles according to the modified set of states.

Abstract: A computer-implemented method for vehicle impact analysis including obtaining a B-Rep representing an outer surface of a vehicle, the B-Rep having faces and obtaining a radius value for a contact sphere. The method also includes determining one or more two-point-contact curves of the B-Rep for the radius value. The determining includes, for each respective two-point-contact curve, solving a respective differential equation based on the B-Rep. The method forms an improved solution for vehicle impact analysis.

Abstract: Embodiments assess vehicle noise. One such embodiment defines a computer-based model of a vehicle and automatically determines aerodynamic performance and propulsion performance of the vehicle based on the defined computer-based model. Responsively, a flight-dynamics simulation of the vehicle is performed using the determined aerodynamic performance and propulsion performance. Performing the flight-dynamics simulation produces flight status data. The flight status data is automatically down-sampled to generate a reduced dataset. A high-fidelity flow simulation of the vehicle is performed using the reduced dataset. Performing the high-fidelity flow simulation determines in-flight aerodynamic and aeroacoustic performance of the vehicle. In turn, based on the determined in-flight aerodynamic and aeroacoustic performance, noise physical characteristics of the vehicle are determined and an indication of the determined noise physical characteristics is stored in computer memory.

Abstract: A computer-implemented method for designing a 3D modeled object. The 3D modeled object represents a mechanical part formed in a material having an anisotropic behavior with respect to a physical property. The method includes obtaining a 3D finite element mesh and data associated to the 3D finite element mesh. The data associated to the 3D finite element mesh includes a plurality of forces and boundary conditions. The plurality of forces forms multiple load cases. The method further comprises optimizing an orientation field distributed on the 3D finite element mesh with respect to an objective function. The objective function rewards orientation continuity with respect to the physical property. The optimizing is based on the 3D finite element mesh and on the data associated to the 3D finite element mesh. This constitutes an improved method for designing a 3D modeled object.

Abstract: A computer-implemented method designs a tying bar enclosing a plurality of concrete-reinforcing bars in a 3D scene of a computer-aided design system. The method a) provides the three-dimensional models of the concrete-reinforcing bars to be enclosed by the tying bar; and b) computes a set of traces of each of the concrete-reinforcing bars. Each trace has a trace center. Next a set of connection lines is computed. Each connection line binds the trace centers. A set of circular arcs is computed. Each circular arc surrounds at least partially a respective trace, and a set of segments. Each segment is approximately parallel to a respective connection line and connects consecutive circular arcs. The segments and circular arcs form a center curve of the tying bar in the sketch plane. Lastly, the tying bar is designed based on the center curve and the bar radius of the tying bar.

Abstract: A method automatically propagates corner connection elements in a 3D modeled object having a plurality of corners with a plurality of structural corner-members. A list of the corners and a selection of a seed corner are received. A target corner in the model is identified as topologically similar to the seed corner. Reference data is collected for a first connection element at the seed corner. The first connection element reference data is copied and oriented to the target corner. A second connection element identical to the first connection element is created and applied to the target corner.

Abstract: A system and method provide access by a web application running on a host computing device in communication with a remote server to a native binary DLL. A browser extension to the web application and a native messaging application communicate with the browser extension via standard input/output. A long-running computational process on the host computing device configured as a wrapper for the binary DLL is executable by the host computing device. The native messaging application and the long-running computational process communicate with one another via a named pipe, and the long-running computational process duration is independent of the native messaging application duration.

Abstract: A computer-implemented method including obtaining a mesh representing a segment of an outer surface of a portion of a mechanical part. The method further including determining curves over the mesh that each follows maximal curvature directions of the mesh, fitting each curve with a respective circle, thereby obtaining a set of circles, and calculating a value of one or more statistics of the set of circles. The method then detects whether the mesh is a fillet or not as a function of the value of the one or more statistics.
