Abstract: A method for efficient distributed object manager (DOM) owner migration in a virtual storage area network (VSAN) is provided. Embodiments include determining to migrate a DOM owner object from a source DOM owner server to a destination DOM owner server. Embodiments include determining that an input or output (I/O) operation affecting the DOM owner object is in progress. Embodiments include, prior to updating the DOM owner object based on the I/O operation, transferring the DOM owner object from the source DOM owner server to the destination DOM owner server. Embodiments include completing execution of the I/O operation on the destination DOM owner server. Embodiments include updating the DOM owner object on the destination DOM owner server based on the I/O operation.

Abstract: Shape diameter-based approaches to identifying and correcting 2D slices of 3D models (or the 3D models themselves) are provided for improved manufacturability. Using the present approaches, critical error-prone regions in 2D slices or 3D models can be identified, including thin extrusions and bridges, sharp corners, small holes, and narrow intrusions. The areas of these regions can be computed and used to quantify the printability of the slices or models. The boundaries of slices or models can be modeled as mass-spring-damper systems for performing local deformations to correct error-prone regions. External forces, that are a function of shape diameters and interior angles, can be imposed on the modeled systems for this purpose.

Abstract: A method of additively manufacturing a 3D structure, comprising defining a boundary conditions, load constraints, and a periodic cell structure for lattifying the 3D structure; providing a surrogate FE model predicting a relationship between the boundary conditions, load constraints, periodic cell structure, and 3D orientation angle of the periodic cell structure; optimizing lattification of the 3D structure, according to orientation angle, and a cost function while meeting the load constraints; and additively manufacturing the optimized 3D structure, optimized e.g., for mass and stress concentration under a pre-determined loading condition.
