摘要： A system and method is provided for element quality improvement in three-dimensional (3D) quadrilateral-dominant surface meshes. The system may include a processor configured to collapse a first plurality of edges of a plurality of quadrilateral elements that form a surface mesh of a 3D model, which edges have lengths that are shorter than a predetermined fraction of a minimum element edge length (MEL). Further, the processor may also move nodes connected to at least some of a second plurality of edges of the plurality of quadrilateral elements so as to have lengths that are at least the MEL. Also, the processor may adjust included angles and the warp of elements to be within predetermined limits. Further, the processor may collapse in the mesh all remaining edges of the plurality of quadrilateral elements that are shorter than the MEL to produce a modified surface mesh in which all quadrilaterals in the modified mesh have edge lengths that are at least the MEL.

摘要： A system and method are provided for adaptive domain reduction for thermo-structural simulation of an additive manufacturing process. The system may include a processor configured to carry out a simulation of a part being additively produced according to a set of tool paths. The simulation may include determining an original mesh of the part; determining an order of the elements of the original mesh to deposit; and simulating an incremental deposit of each of the elements of the original mesh for a material in the order that the elements are determined to be deposited. For each incremental deposit of an additional respective element the processor may determine thermal characteristics and structural deformation characteristics of the deposited elements. After the deposit of several layers have been simulated, subsequent simulation of elements may be carried out based on a respective modified version of the original mesh in which at least some of the layers of the original mesh previously simulated to be deposited under a current layer are retained and at least some are omitted.

摘要： Method, systems, and processes are provided for generating a model having a plurality of represented composite layers, wherein the represented composite layers do not fill one or more inclusions within a structural volume represented within a computer aided drafting (CAD) model representing a composite part. The composite part can then be manufactured, based on the resultant generated model, using any manufacturing technique, including but not limited to, 3D printer, hand layup, automated layup, and other methods for distributing multiple layers of a composite material onto a laminate surface to manufacture a composite part.

摘要： A component of a computer-aided manufacturing (CAM) system may be configured to cause a processor to generate instructions that specify how a 3D-printer additively builds an article on a build plate via depositing material from a deposition head. The 3D printer is configured to cause the deposition head to rotate in order to selectively change, an angle of a deposition axis at which the deposition head outputs material. The generated instructions specify how the deposition head is operated by the 3D printer to build the article on the build plate such that material deposited along a side wall surface of the article is provided by the deposition head having its deposition axis orientated at an angle determined based at least in part on an angular orientation of the side wall surface.

摘要： Methods for modifying geometric models and corresponding systems and computer-readable mediums. A method includes receiving a geometric model, the geometric model including a plurality of curves. The method includes receiving a selection of one or more curves of the plurality of curves, finding at least one other curve of the plurality of curves that is related to the selected curve, and finding relationships between the selected curve and the other curve(s), including adding the selected curve, the other curve(s), and the relationships to a selected curve set. The method includes pre-processing the selected curve set, including de-activating a set of constraints for the geometric model. The method includes receiving a modification of the selected curve and modifying the selected curve set to produce a modified geometric model and modified selected curve set. The method includes post-processing the modified selected curve set, including re-activating and applying constraints for the geometric model.

摘要： Product Data Management (PDM) systems and methods. A method includes receiving a target body and a tool body, and evaluating a body type of the target body and a body type of the tool body. The method includes evaluating interactions between the target body and the tool body, and applying comparison criteria to determine spatial relation and relative convexity of an intersection between the target body and the tool body. The method includes identifying tool face regions of the tool body based on the evaluations and the determined spatial relation and relative convexity of the intersection. The method includes adding the tool face regions to the target body to produce a modified target body.
