Singularities tend to occur in areas where the corner radius is zero or very small on the model!
In CAE, it is said that the finer the mesh size, the higher the analysis accuracy. However, depending on the boundary conditions and model shape, a mesh that is too fine can sometimes actually decrease analysis accuracy. This is known as the existence of "singularities." These are likely to occur in areas where the corner radius is zero or very small. If the stress continues to increase as the mesh size is reduced, it is advisable to suspect this "singularity." Therefore, instead of judging based on the maximum stress at the location with a zero corner radius, it is better to evaluate the stress at a slightly offset location. Additionally, if possible, it is recommended to add a sufficiently large corner radius at the zero corner radius locations and conduct a re-analysis. *For more details, please refer to the related links or feel free to contact us.*

Company information
Sanglory Co., Ltd. was founded in 1940 as a manufacturer of plastic industrial parts. Over the past 80 years, we have made continuous efforts to establish ourselves as a leading company in the manufacturing of precision plastic parts. We maximize the advantages of plastic to realize them in our products and components. To achieve this, we utilize computers as a standard in our development processes and leverage high technical standards and abundant know-how through CAD/CAM and CAE to meet our customers' needs. Our "Process Spirit" focuses on achieving the shortest development lead times by world standards, as well as the modularization of price and functionality that can compete globally, thus realizing "the world's optimal production conditions." To achieve these optimal production conditions, we are expanding our production system globally with a management outlook aimed at the world market, currently establishing production and sales bases in the UK, China, Malaysia, Singapore, Thailand, and other locations around the world.
