[Filters] Sensitivity filter – Top3d

In the topology optimization, filters are introduced to avoid numerical instabilities. Different filtering techniques may result different discreteness of the final solutions, and sometimes may even contribute to different topologies. In this series of tutorial, you will learn how to

[Filters] Grayscale Filter – Top3d

In the topology optimization, filters are introduced to avoid numerical instabilities. Different filtering techniques may result different discreteness of the final solutions, and sometimes may even contribute to different topologies. In this series of tutorial, you will learn how to

Iterative solver – Top3d

If the finite element mesh size becomes large, the traditional direct solver (line 72) used to address the finite element analysis is suffered by longer solving time and some other issues. However, iterative solver can solve large-scale problems efficiently. In

Continuations – Top3d

In this tutorial, you will learn how to apply continuations strategy to derive the final solution to global minima. Convexity is a very preferable property since every local minima is also the global minima, and what the program is solving
