Boundary conditions are probably where most of the engineers get it wrong. Boundary conditions have a great impact on the result of analysis and a simple mistake in BCs makes the difference between a model with 30% of error and 3% of error. Here’s a simple example in which the maximum difference goes up to 1416% (at […]
That FEA problem used to drive me mad It happened to me a countless number of times. I had just finished to set up my FEA model and run the analysis and I knew more or less what range of stresses I wanted to find. I was waiting for the results to confirm that… BUT…As […]
Have you realized how everyone is always talking about FEA as the ultimate weapon to solve any engineering problem? In one direction, that’s true, FEA is very powerful… but there are also some dangers, and no one is talking about them.
Being able to solve FEA problems is a skill, and this skill is trained by knowing the correct process to solve an FEA problem. Those steps are extremely important and if you learn how to develop correctly your thinking to assess each of these steps correctly, you will be able to become very quickly an […]
Buckling is a dangerous phenomenon which can cause sudden failure of the structure, leading to potential economic or even life losses. It is therefore important to understand the buckling behaviors if the design involves slender structures bearing compressive load, that is commonly encountered in large steel structures of marine & offshore, mining and construction industries. […]
CAD model Your model is not meshed properly or the mesher cannot even complete the meshing? This kind of problem happens to everyone, even the most skilled in FEA. Nowadays, CAD models tend to have too many details and so it is difficult for an analyst to simplify those models enough to get a proper […]
