The record

Purpose: TopOpt is an acronym for Topology Optimization, and the DTU group develops and applies density based topology optimization methods.
Group: The group is a joint research effort between DTU Mechanical Engineering and DTU Compute.
Interactive apps: The site lists 2D and 3D interactive TopOpt apps for handheld devices and web.
Mobile platforms: The 3D app is listed for iOS, Windows, and Mac OSX; the 2D app is listed for iOS, Android, Linux, Mac OSX, and Windows.
MATLAB code: The page offers MATLAB codes for minimum compliance problems and Python code described as a 200-line implementation for minimum compliance problems.
Educational audience: The 99-line MATLAB code is intended for engineering education and is offered to students and newcomers to topology optimization.
Large scale framework: The PETSc-based code is a fully parallel framework for very large scale topology optimization on structured grids.
Framework components: The PETSc framework includes mesh and optimization parameters, a 3D linear elasticity solver, standard and PDE based filters, parallel MMA, and IO and Python script converters.
Integrations: The PETSc framework is built upon PETSc, and the page recommends ParaView version 4.0 or newer for visualization.
Photonics: The photonics offering includes a 200-line MATLAB TopOpt code for 2D cylindrical metalens design and five COMSOL Multiphysics models.
Buckling optimization: TopBuck250 extends top99neo to 2D buckling problems and supports buckling load factor maximization and minimum volume design with compliance and buckling constraints.
Grasshopper: The Apps/Software page lists TopOpt for Grasshopper and links to a Grasshopper project page.
Platform requirements: The Windows downloads for the 2D and 3D apps require VC++R2012 and VC++R2013.
Security and support: The opened maker pages provide no security or compliance statements and list no support plan.
