![]() There is a new 3D topology optimization tutorial model in the Application Library that illustrates the new feature and best practices for exporting and importing STL-files of the resulting designs. Using this feature is preferable to the other types of regularizations (for example, Tikhonov regularization) that is used in tutorial models in previous versions of COMSOL Multiphysics ®. ![]() These topology optimization improvements are thanks to a new Density Model feature that introduces a minimum length scale: the filter radius. All Answers (1) there a paper Simulation for Thermomechanical Behavior of Shape Memory Alloy (SMA) using COMSOL Multiphysics by Shamit Shrivastava. Topology optimization for structural mechanics and fluid flow now involves substantially less trial and error. Density Model Feature for Topology Optimization The Method editor is an important part of the Application Builder and is available in the COMSOL Desktop environment in the Windows version of COMSOL Multiphysics. By combining the Composite Materials Module with the Heat Transfer Module, you get more sophisticated heat transfer and thermal expansion functionality. This book is a guide to writing code for COMSOL models and applications using the Method editor. ![]() ![]() Read more about these optimization features below. This module is useful for structural analysis of composite laminates, and can be coupled to the Heat Transfer Module and the AC/DC Module for multiphysics analysis of composite materials. For users of the Optimization Module, COMSOL Multiphysics ® version 5.4 includes a Density Model feature for topology optimization, the ability to combine a Parametric Sweep study with derivative free optimization, and new models to demonstrate the Density Model feature.
