Femap Bolt Preload Tutorial

I think that many engineers, especially in the structural field, start FEA to calculate complex connections. There are few traps on such problems, and one of them is preloading bolts! This is why I've created a tutorial to do just that in Femap! I hope you will like it! There are several ways in which [...]

Fundamentals of Finite Element Analysis: Complete Beginners Guide

There is no doubt in my mind that Finite Element Analysis (FEA) is the cornerstone of my career. I attribute most of my career successes to both engineering and FEA knowledge. However, when I started, I really hated FEA... it was an intimidating thing I had to do for my Ph.D... and I almost exclusively [...]

FEA analysis won’t run? Fix it with this #FEAchecklist!

It's time for the second part of the #FEAchecklist! Last time we were checking stuff before starting an analysis. Now, let's wonder what to check if you see analysis errors when your analysis fails to run. I can honestly say I'm kind of an expert here... I'm pretty certain I've made most of the possible [...]

Before you run an analysis: #FEAchecklist!

My friend and employee Asia just started a maternity leave. Since she was also responsible for training our new team member, in her "casual-self" brilliance she left her an "FEA with no stress" checklist. I've read it, and it's so awesome that I simply have to share it with you! It also gives me a [...]

Flow Chart: Do I need contact

Download the printer-friendly version here, and read the user guide below! We will tackle contact here. If you haven't read my posts on nonlinear supports and how to avoid contact you may find them interesting : ) This is not the first flowchart that I posted here. You can also check flow charts for nonlinear [...]

Nonlinear supports in FEA: Gap Elements (NX Nastran) [Q&A #2]

Recently I got a great question from Ardalan (thanks for writing mate!) about defining nonlinear supports in FEA. I think he does a better job of defining the problem: First how to constraint an entity with in tolerance rather than completely fixing it? i.e. how to define a certain range of motion for an entity [...]

When to ignore contact in FEA?

Linear FEA calculations are the most common type of static analysis done with finite elements. So far we have discussed when it is safe to ignore material nonlinearity and when to ignore geometric nonlinearity. Ignoring those aspects allow you to use linear analysis which is a simple yet robust tool. There is another thing we should [...]
