A number of these schemes relied on the presence of a Cartesian grid on which the doping scalar fields would be defined, such as the junction and impurity refinement. In addition to this, Victory Mesh now supports the loading and refinement of individual structure files which include arbitrary scalar data, such as those produced by Victory Device. This allows refinement on device quantities to accelerate and enhance convergence of simulations.<\/p>\n<p>Victory Mesh also includes a new Delaunay refinement scheme based on the integral of the gradient of a scalar field over a mesh element. This increases the mesh density where the scalar field is varying most quickly with the result of equalising this gradient measurement on elements of the mesh. This leads to improved results in device simulation where the scalar field is chosen to be<br \/>\none which is important for convergence.<\/p>\n<p><img loading=\"lazy\" width=\"546\" height=\"719\" src=\"https:\/\/silvaco.com\/wp-content\/uploads\/simulationstandard\/simstd_Q2_2020_a2.jpg\" class=\"cleaned-enfold-image\" alt=\"\" decoding=\"async\" loading=\"lazy\" srcset=\"https:\/\/silvaco.com\/wp-content\/uploads\/simulationstandard\/simstd_Q2_2020_a2.jpg 546w, https:\/\/silvaco.com\/wp-content\/uploads\/simulationstandard\/simstd_Q2_2020_a2-228x300.jpg 228w, https:\/\/silvaco.com\/wp-content\/uploads\/simulationstandard\/simstd_Q2_2020_a2-535x705.jpg 535w, https:\/\/silvaco.com\/wp-content\/uploads\/simulationstandard\/simstd_Q2_2020_a2-28x37.jpg 28w, https:\/\/silvaco.com\/wp-content\/uploads\/simulationstandard\/simstd_Q2_2020_a2-42x55.jpg 42w, https:\/\/silvaco.com\/wp-content\/uploads\/simulationstandard\/simstd_Q2_2020_a2-36x48.jpg 36w\" sizes=\"auto, (max-width: 546px) 100vw, 546px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>2020 TCAD Baseline Release<br \/>\nSection 2: Meshing \u2013 New Features in 2020 Baseline Release<\/p>\n","protected":false},"author":3,"featured_media":22468,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[7723],"tags":[],"class_list":["post-35552","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-simulation-standard-zh-hans","entry","has-media"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.7 (Yoast SEO v28.7) -
