Abstract: One goal in automated product designing of additive manufacturing is to obtain designs having overhangs without support structures if the criterion for overhangs is rigorously geometrical. In an embodiment of the present invention, designers can request automated optimization and design, using simulation and sensitivity-based optimization, of structures having overhangs in the print direction that do not need any support structures. In an embodiment, a method includes, at a processor, calculating model design responses and model sensitivities of a computer-aided engineering (CAE) model in a CAE system based on design variables of the CAE model for various design responses being either applied in objective or constraints. The method further includes optimizing values of the design variables. The method further includes calculating physical design variables by employing a penalty function. Additionally, the calculations can also be in conjunction with employing material interpolation schemes. The method further includes generating an optimized CAE model using the calculated physical design variables. The optimized CAE model is free or partly free of support structures. The method further includes printing the optimized CAE model being free or partly free of support structures.

Abstract: The invention notably relates to a computer-implemented method for designing an outer surface of a composite part manufactured by molding a stack of material layers. The method comprises defining constant offset surfaces, a constant offset surface being a respective part of the outer surface which is to have a constant offset value relative to the reference surface, the constant offset value of a respective constant offset surface corresponding to the sum of the thicknesses of the material layers below the respective constant offset surface, and determining a final surface that corresponds to a tangent continuous connection of the constant offset surfaces. This provides an improved solution for designing an outer surface of a composite part.

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 invention notably relates to a computer-implemented method for recognizing a three-dimensional modeled object from a two-dimensional image. The method comprises providing a first set of two-dimensional images rendered from three-dimensional modeled objects, each two-dimensional image of the first set being associated to a label; providing a second set of two-dimensional images not rendered from three-dimensional objects, each two-dimensional image of the second set being associated to a label; training a model on both first and second sets; providing a similarity metric; submitting a two-dimensional image depicting at least one object; and retrieving a three-dimensional object similar to the said at least one object of the two-dimensional image submitted by using the trained model and the similarity metric.

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 displays an assembly of digitally modeled objects in a three-dimensional scene, by the steps of: defining at least one object of the assembly as being revealable; generating a graphical representation of the assembly wherein said revealable object is located at least partially behind at least another object, called hiding object, and displaying said graphical representation; using a graphical tool selecting a region of said graphical representation of the assembly, called a revealing zone; and rendering a three-dimensional scene comprising a three-dimensional representation of the assembly wherein a portion of the revealable object located behind the hiding object and comprised within the revealing zone is shown by transparency through said hiding object. A computer program product, a non-volatile computer-readable data-storage medium and a Computer Aided Design system for carrying out such a method.

Abstract: A method and corresponding system upgrades a live computer system. The method begins with migrating a copy of data from a first system to a communicatively coupled second system at a first time. Next, at one or more subsequent times, a copy of changed data is migrated from the first system to the second system until a threshold is reached. Finally, in response to reaching the threshold, a copy of the remaining changed data is migrated from the first system to the second system. A further embodiment of the method comprises: disabling access to the first system during the migration of data at the first time, enabling and maintaining access to the first system at the one or more subsequent times during the migration of the copy of changed data, and disabling access to the first system during the migration of the copy of the remaining changed data. In this manner, the system being upgraded is still highly available throughout the upgrade process.
