The performance improvement of competitive three-dimensional puzzles has greatly contributed to shortening solving times. Through analysis using the dynamic explicit method, we delve into the secrets of their smooth rotation.

A slap band wraps around an arm or other object when struck. It is a bistable structure that remains stable both when extended and when rolled up. This article explains the principles behind slap bands and similar structures.

Have you ever experienced using topology optimization? Some of you might have used commercial software but may not fully understand the internal workings or specific features of different methods. In this article, we will explain the characteristics of typical topology optimization methods in a simple manner, implement two of them, and compare the results.

This article is the second part of a blog introducing Lattice Structure Homogenization. In the first part, we introduced the homogenization of lattice structures as elastic bodies. In the second part, we will introduce the homogenization of channels created by lattice structures, including the homogenization process through numerical experiments and visualization of the homogenization results.

Have you ever done an analysis on a lattice structure? Lattice structures tend to be difficult to mesh and computationally expensive. Homogenization is an effective way to reduce the analysis cost of lattice structures. This article introduces homogenization to elastic matrices by numerical experiments and visualization of the homogenized elastic matrices.

Have you ever performed optimization in Grasshopper? Specifically, have you used Tunny for optimization? During that time, did you ever feel that the optimization was not working well? The category of optimization called black-box optimization, which Tunny uses, has slower convergence compared to sensitivity-based optimization (such as topology optimization). If the settings are not properly configured or the problem is not suitable, the result may end up being just slightly better than random. In this article, let's look at the optimization results using Tunny with different settings.

This article presents an example of a design flow using an in-house design environment, with one specific design case study.

This article considers the importance of material models in numerical analysis through the modeling of lunar soil (Regolith) and dynamic analysis of drop tests.

This is the second installment of our project to think about structural mechanics while taking a walk. This time, while walking around Japanese towers, we will explain the mechanics and structural devices behind the towers and ponder the greatness of our predecessors. After reading this, you should be able to see the framework of the tower through the tower.

In this article we run geometry optimization using OpenFoam CFD results + Grasshopper.
