Топологическая оптимизация в FEATool

Heaviside projection based topology optimization by a PDE-filtered scalar function - Structural and Multidisciplinary Optimization This paper deals with topology optimization based on the Heaviside projection method using a scalar function as design variables. The scalar function is then regularized by a PDE based filter. Several image-processing based filtering techniques have so far been proposed for regularization or restricting the minimum length scale. They are conventionally applied to the design sensitivities rather than the design variables themselves. However, it causes discrepancies between the filtered sensitivit link.springer.com https://www.featool.com/model-showcase/03_Structural_Mechanics_07_topology_optimization1/ www.featool.com

В связке FEATool Multiphysics + Matlab или Octave оказывается доступна оптимизация топологии. Шинтаро Ямасаки (Shintaro Yamasaki) из университета Осаки (Osaka University) подготовил учебный пример по тому, как можно решить задачу оптимизации топологии. К сожалению, статья описывающая постановку платная: https://link.springer.com/article/10.1007%2Fs00158-010-0562-2, однако ссылка на сам m-script, выполняющий тестовый пример в FEATool, публично доступна: http://www.featool.com/download/optexec.m
