Explicit analysis are a technique that helps model fast and intense events by directly solving motion equations step by step. This is especially useful for studying crashes, explosions, and other dynamic processes. OpenRadioss The most well-known and used explicite solvers are: LS-Dyna, Abaqus Explicte, Radioss (Altair) and Autodyne (Ansys). In 2022, Altair decided to release…
I often read that free programs for FEA are good, but not for shell calculations. That’s where you need a proven, paid solver. In this article I want to check this, “Are open source programs (Code Aster and Calculix) suitable for shell calculations?”. Shell elements Shell elements are a type of finite element used in…
In an article with free FEM packages, I listed three programs worth looking into (link to article): Salome Meca, PrePoMax and Freecad Workbench FEM. In today’s article I will describe the second of these. About PrePoMax PrePoMax is a pre and post processor for the Calculix solver. It has recently become more popular and is…
Salome or Salome Meca? Or maybe Code Aster? I often see mistakes in understanding the names of these programmes, so today I will try to explain this. The article is a repeat of the knowledge included in two already published articles (1 and 2) but here I will present it in a broader form. You…
Hi, today is the second part of the article about open source solutions in FEM. In part one, I presented the most important free programs that are individual parts of FEA systems (geometry, mesh, solvers, postprocessor). In this article, I will describe programs that are whole FEM packages. Salome-Meca The first program is Salome-Meca. It…
Hi, Tom here. The first article on this site will be an overview of available open-source (free) finite element analysis software. In the article about me, where I described what I will be doing on the blog, I tried to explain what an open-source license type is using definitions. I quickly noticed that I am…
