A method of 3D printing a part using a photopolymer build material including the steps of characterizing a three-dimensional curved surface using a mathematical equation and a specification; characterizing at least one surface transition between at least two parallel slice planes that intersect the ...
plastic molds, and CNC-machined parts. ZW3D has many functions for creating curves easily in 2D and 3D, such as lines, circles, arcs, ellipses, spirals, and splines. While these functions satisfy basic modeling needs, they do not make it easy to create curved shapes like 3D Archimedes...
You can find some examples on creating complicated geometry starting from primitive shapes. Few complicated examples: https://www.mathworks.com/help/pde/ug/battery-module-geometry.html https://www.mathworks.com/help/pde/ug/battery-module-cooling-analysis-and-reduce...
A very wide range of physical processes lead to wave motion, where signals are propagated through a medium in space and time, normally with little or no permanent movement of the medium itself. The shape of the signals may undergo changes as they travel through matter, but usually not so mu...

complex aerodynamics shapes. This is mainly due to the promise that the construction of an unstruc- tured grid around complex configurations such as an aircraft requires much less time than a comparable block-structured grid. Furthermore, local refinement of unstructured grids can be carried...
