Freeware CAD and FEA 2020 – Part 1: User friendly options

FEA and stress analysis, Uncategorized
A familiar commercial software can boost engineers productivity to a maximum. The downside is cost, especially for research and education projects. The good news for 2020: We found that some GNU software evolved to user friendly products, suitable for a variety of problems and user knowledge levels. This article outlines our opinions, hints and conclusions regarding FreeCAD, GMSH and Salome Meca open source suftware. Intro Being involved in any kind of engineering, either by profession or as a hobby, you have probably faced the challenge of choosing a CAD software for: making a drawing, preparing a model for your 3D printer, simulating an object for stress analysis (FEA), solving a fluid-structure simulation using parallel computing maybe, and more... Is there any 'best-of-the-best' software package to do it all? Perhaps yes,…

FEA Nocturne – Time for Change?

FEA and stress analysis, Uncategorized
Finite Element Analysis (FEA) is indispensable for visualizing a structural response to a wide spectrum of loads and design options. FEA enables plotting a stress/strain field for complex geometries, which is not feasible to do by hand calculations. It appears that FEA services lose popularity in our industry. Here I share my thoughts why this happened, and conclude on how to improve the FEA practicality and to embed it into the plant asset management process. Here we will start from deep technical matters and end up with bright future perspectives. Tips are for FEA practitioners only. Fig. 1. FEA analysis loop, as it should be Introduction - What is FEA at a glance? Structural Mechanics force, displacement and stress calculations are well suitable for simple, idealized objects like beam frames…
