Klipper is an open source firmware for 3D printers that distributes the workload between a general-purpose computer (such as a Raspberry Pi [1]) and one or more underlying microcontrollers on the 3D printer. [2] [3] The separation claims to allow for more advanced control compared to traditional firmware that runs solely on the printer's ...
An algorithm generating a mesh is typically controlled by the above three and other parameters. Some types of computer analysis of a constructed design require an adaptive mesh refinement, which is a mesh made finer (using stronger parameters) in regions where the analysis needs more detail. [1] [2]
Adaptive mesh refinement (AMR) changes the spacing of grid points, to change how accurately the solution is known in that region. In the shallow water example, the grid might in general be spaced every few feet—but it could be adaptively refined to have grid points every few inches in places where there are large waves.
SALOME is a multi-platform open source (LGPL-2.1-or-later) scientific computing environment, allowing the realization of industrial studies of physics simulations.. This platform, developed by a partnership between EDF and CEA, sets up an environment for the various stages of a study to be carried out: from the creation of the CAD model and the mesh to the post-processing and visualization of ...
A general guide has been provided as a design principle to achieve parameters (e.g., mesh size and physical parameters such as Poisson's ratio that appear in the nearly singular operator) independent convergence rate of the multigrid method applied to such nearly singular systems, [24] i.e., in each grid, a space decomposition based on which ...
A coarse mesh may provide an accurate solution if the solution is a constant, so the precision depends on the particular problem instance. One can selectively refine the mesh in areas where the solution gradients are high, thus increasing fidelity there. Accuracy, including interpolated values within an element, depends on the element type and ...
The system allows its operator to "grab" a thermal image from a vehicle or other object for display. [6] Adaptiv was developed by BAE Systems AB's survivability programme at Örnsköldsvik, Sweden, initially for Combat Vehicle 90 infantry fighting vehicles. [4] The company has developed a lighter version which has been tested on helicopters.
ANSA is a computer-aided engineering tool for finite element analysis and computational fluid dynamics analysis widely used in the automotive industry. It is developed by BETA CAE Systems. The software is distributed world wide by a number of BETA CAE Systems subsidiaries and business agents.
