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…
Hi, welcome to you after a short break, hopefully I will now get back to posting regularly 🙂 While writing article PrePoMax – the best open source FEA software? I tried to answer this question and I am still not sure of the answer. However, I can write with certainty that PrePoMax is currently the…
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…
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…
Salome Meca is an open source FEA package integrating Salome (pre- and post-processor) and Code_aster (solver). It is a free finite element analysis program with the greatest calculation capabilities. You can read more about Salome-Meca and other packages in my review of open source FEM analysis packages. The latest version of Salome Meca is 2021.1….
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…
