Nowadays, no software product can be apart from open source projects or communities, and many large software and technology cooperations are also active contributors to open source projects and platforms. WelSim has always been a supporter of the open source community, especially for those friendly open source licenses such as…

The latest release boosts meshing using the HDF5 data exchange format. BRIDGEVILLE, PA, July 25, 2022 — WELSIMULATION LLC is thrilled to release version 2.3 of WELSIM — a general-purpose engineering simulation software. Engineers and researchers can conduct more complicated simulation studies with today’s release of WELSIM v2.3. WELSIM continues…

The beam is a specific structure commonly used in engineering. The beam can be made as an independent beam or can be combined with other structures such as plate, shell, or concrete solid structure to form an integral beam or multi-layer frame. Due to the wide application of beams, the…

Modern electromagnetic research has penetrated various fields. In recent years, with the rapid development of new technologies such as 5G, electric vehicles, and IoT, the role of electromagnetic analysis has become more and more important. Electromagnetics simulation has been widely and successfully applied to many aspects of electromagnetic performance prediction…

With the development of computer graphics, hardware, and 3D printing technology, graphic rendering and its file format based on surface triangle mesh have become more and more popular. In finite element analysis (FEA), engineers sometimes get geometry files based on triangle meshes (such as STL files, etc.) and perform subsequent…

Curve fitting is a numerical process often used in data analysis. Its essence is to apply a certain model (or called a function or a set of functions) to fit a series of discrete data into a smooth curve or surface, and numerically solve the corresponding parameters, thereby obtaining the…

When a finite element analysis model contains hyperelastic materials, engineers usually have little substantial data to help get the results. Sometimes a lucky engineer will have some tension or compression stress-strain test data, or simple shear test data. Processing and applying these data is a critical step to analyze the…

In previous articles, we have introduced Arruda-Boyce, neo-Hookean, Mooney-Rivlin, Yeoh, Gent, Blatz-Ko and other hyperelastic models that often used in nonlinear finite element analysis. Now we will be discussing a special and widely applied hyperelastic model: Ogden. A versatile model that can be used for rubber, polymer, and biological tissues…
