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.

Using Shimenawa decorations as a subject, this article introduces the theory and simulation methods of deformation for flexible rod-like objects.

Most of the hinge caps used in condiments and cosmetics have an open/close mechanism achieved by bistability. This article introduces bistable hinge caps from a mechanical point of view.

Is everyone using ChatGPT? Various uses and updates are making the rounds on the Internet on a regular basis, but you may not think that Rhino and Grasshopper have much to do with it. There are already plug-ins available that use ChatGPT to control Rhino and GH, though not necessarily in a stable manner. If you check how it works with your familiar software, you will feel more familiar with ChatGPT. Let's check the implementation of existing plug-ins and see how they work.

Our company develops various products by utilizing shape processing technology, functional calculation technology, and design technology. In this article, we present a case study of a heat sink design that was designed by interweaving thermal fluid topology optimization and human knowledge.

This is a travelogue in which our structural engineer takes four bridges in Tokyo as examples and explains their structures as he travels around the city. The scenery you usually see may look a little different. Please enjoy the idyllic atmosphere.

In this article we caluclated CFD by OpenFOAM as a first step to do geometry optimization.

For folding hangers designed by applying compliant mechanism, we will confirm the cost reduction effect by compacting parts.

This article introduces Tunny, Optuna's 3D CAD wrapper. We will start with an introduction of Rhinoceros, a 3D CAD software on which Tunny runs. Then, I will provide a brief overview of how I implemented Tunny. Finally, I will walk you through some design examples using Tunny, including crash safety design of a car front bumper in connection with CAE, and Human-in-the-loop optimization of vase shapes and architectural column placement.
