Rotation by 90° about the origin: R (origin, 90°) A rotation by 90° about the origin can be seen in the picture below in which A is rotated to its image A'. The general rule for a rotation by 90° about the origin is (A,B) (-B, A) Rotation by 180° about the origin: R (origin, 180°)
Patterned cell divisions require a precisely oriented spindle that segregates chromosomes and determines the cytokinetic plane. In this study, we investigated how the meiotic spindle orients through an obligatory rotation during meiotic division in mouse oocytes. We show that spindle rotation occurs at the completion of chromosome segregation, whereby the separated chromosome clusters each ...
Rotating Cylinders, Annuli, and Spheres Flow over rotating cylinders is important in a wide number of applications from shafts and axles to spinning projectiles. Also considered here is the flow in an annulus formed between two concentric cylinders where one or both of the cylindrical surfaces is or are rotating.
Translation and/or rotation – Shape and size of the body do not change Deformation – A vector that represents a movement of a point in a body (due to applied loads) relative to another body point – The shape and size of the body change (being deformed) – Volume may be unchanged (special cases) – Strain – Intensity of deformation
Tools for Designing and Optimizing Multibody Systems. The Multibody Dynamics Module is an add-on to the COMSOL Multiphysics software that provides an advanced set of tools for designing and optimizing multibody structural mechanics systems using finite element analysis (FEA).

Comsol Multiphysics 5.3 | 4.1 Gb COMSOL, the leading provider of multiphysics modeling and simulation software, has released version 5.3 of COMSOL Multiphysics software, is a general-purpose software platform, based on advanced numerical methods, for modeling and simulating physics-based problems. This release provides you with notable performance improvements as compared to earlier versions.
Hello Everyone :smileyhappy: I created a dynamic block (light pole) which have a stretch parameter for height adjustments. This can only be done with the pole laying down, so everytime the block is inserted it always needs to be 3d rotated. I found a routine that Lee Mac wrote which works really w...When a symmetric object is rotating, Coriolis forces break the symmetry between sound waves generated by the object, splitting their frequencies in proportion to the rate of rotation. Measuring the difference in frequency of the broken degenerate modes can tell us the rate of rotation. If you toss a cellphone, tennis racket, wingnut, cereal box, or any object with 3 axes of rotation in the air, it will demonstrate this interesting and unusual effect… The rotating and fixed parts need to be coupled together by an identity pair, where a flux continuity boundary condition is applied. You can use the rotating machinery predefined multiphysics coupling in cases where it is possible to divide the modeled device into rotationally invariant geometries. If you toss a cellphone, tennis racket, wingnut, cereal box, or any object with 3 axes of rotation in the air, it will demonstrate this interesting and unusual effect… A Simulation App for Helical Spring Design and Analysis deterioration of insulation as a function of time. PD, in rotating machines, is caused by the electric field being high enough to locally break down the air that is adjacent to the solid insulation. In rotating machines there are several places where PD might be present in a coil or winding.
