An exploratory study was conducted on developing a conditional GAN–based generative model for generating corrugated plate geometries conditioned on target bending stiffness.

We have conducted many projects in the field of vibration and acoustics, such as vibration reduction and noise reduction of machinery. One of the most widely used methods is vibration and acoustic simulation using the finite element method. In this article, we will use a simulation of an acoustic guitar using the finite element method as an example, and briefly explain how we utilize simulation to evaluate vibration and acoustic characteristics, and what kind of physics exists behind the beautiful sound of a guitar.

The theme of this article is "Boundary processing of pixel images using the marching squares method." How can we create boundaries and interfaces that look smooth and natural to the human eye from the scalar field information obtained on a lattice? We will understand the algorithm and implement it in Grasshopper, then evaluate its application to various shapes.

Most houses in Japan are constructed of wood, and structural calculations that take into account earthquake and wind resistance are essential for their design. Especially for low-rise wooden houses, wall volume calculations and eccentricity considerations based on the Building Standard Law are important factors. This article summarizes the basic concepts in structural design of wooden houses and introduces the optimization of structural design of low-rise wooden houses using Grasshopper. It should be of interest to those involved in structural design and those interested in improving the efficiency of design methods.

At Nature Architects, many professional projects are carried out, but hobby projects occasionally emerge as well. This article introduces the puzzle craze that occurred within the company last year.

Optuna, widely used for solving optimization problems, has recently been updated to version 4, introducing a new feature called OptunaHub. Taking this opportunity, we have published an implementation of the multi-objective optimization algorithm "MOEA/D" through OptunaHub. In this article, we introduce the characteristics of MOEA/D and present an example comparison with other optimization methods. Those interested in evolutionary multi-objective optimization or seeking more efficient optimization techniques may find this article useful.

This article examines the utility of deriving estimations of target values by applying publicly accessible information to theoretical models as a preliminary step prior to conducting a numerical simulation.

Structural analysis uses the finite element method, while fluid analysis uses the finite volume method. Why are different methods commonly used for structure and fluid analysis, even though both are the same in the sense that they are methods for solving partial differential equations discretely? In this article, we compare the finite element method and the finite volume method in fluid analysis and give a glimpse into the reason “why the finite volume method became common in CFD."

In this article, I will take "Hiragana" as an example of shape exploration and investigate it. After reading this, you will surely want to know more about the shapes around you.
