Numerical solution of the Monge–Ampère equation on the surface of a sphere. • Optimal transport for mesh adaptation. • New linearisation of the Monge–Ampère equation and exponential maps. • Proof of existence of solutions. • Comparisons with centroidal Voronoi tessellations on the spher...
A flexible shape-definition tool for surface modeling using Coons patches is considered to represent the shape and the thickness distribution of the structure, followed by an automatic mesh generator for structured meshes on the shell surface. Nine-node quadrilateral Mindlin鈥揜eissner shell elements ...
As the spherical surface is non-Euclidean, a well-defined grid with more than 12 points, meting the two attributes simultaneously, cannot be constructed on a sphere [20]. However, the area uniformity and the interval uniformity of the spherical grid can be trade off to enhance extremely the ...
The technique used from [34] is summarised below: • determine the four external points of the set, discarding all points interior to the convex quadrilateral they form, • break points into four regions that can be solved separately, • use vector crossproducts to determine feasible convex...
diving tubular pump; energy loss; entropy generation; surface response method; pump hydraulic performance1. Introduction A tubular pump is a pump with a built-in motor. Because the inlet and outlet channels of the pump are in a straight line, the tubular pump is widely used in the fields ...
