It is developed by Pixar and was first published as open source software in 2016, under a modified Apache license. [4] Pixar, Adobe, Apple, Autodesk, and NVIDIA, together with the Joint Development Foundation (JDF) of the Linux Foundation, announced the Alliance for OpenUSD (AOUSD) on August 1, 2023 to "promote the standardization, development, evolution, and growth of Pixar's Universal Scene ...
In uniform scaling with a non-zero scale factor, all non-zero vectors retain their direction (as seen from the origin), or all have the direction reversed, depending on the sign of the scaling factor. In non-uniform scaling only the vectors that belong to an eigenspace will retain their direction. A vector that is the sum of two or more non ...
Autodesk Simulation is a general-purpose multiphysics finite element analysis software package initially developed by ALGOR Incorporated and acquired by Autodesk in January 2009. [ 1 ] It is intended for use with Microsoft Windows and Linux operating systems .
When composing multiple linear transformations, it is possible to create a shear/skew by composing a parent transform with a non-uniform scale, and a child transform with a rotation. Therefore, in situations where shear/skew is not allowed, transformation matrices must also have uniform scale in order to prevent a shear/skew from appearing as ...
Geometrically and materially nonlinear analysis with imperfections included (GMNIA), is a structural analysis method designed to verify the strength capacity of a structure, which accounts for both plasticity and buckling failure modes.
Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces. It offers great flexibility and precision for handling both analytic (defined by common mathematical formulae ) and modeled shapes .
Isogeometric analysis is a computational approach that offers the possibility of integrating finite element analysis (FEA) into conventional NURBS-based CAD design tools. . Currently, it is necessary to convert data between CAD and FEA packages to analyse new designs during development, a difficult task since the two computational geometric approaches are diffe
In fluid mechanics, non-dimensionalization of the Navier–Stokes equations is the conversion of the Navier–Stokes equation to a nondimensional form. This technique can ease the analysis of the problem at hand, and reduce the number of free parameters. Small or large sizes of certain dimensionless parameters indicate the importance of certain ...
