Hello everyone!
What do you think about the performance of wedge elements? I know that element choice is case-dependent but I’m looking for some general recommendations that can be followed in most cases before going into details and mesh convergence studies (like the recommendation that hex...
Hello everyone!
I’ve read some articles about the 3-2-1 method, like this one: https://www.digitalengineering247.com/article/free-floating-fea-models
However, I wonder how to use this approach for a simple pressure vessel analysis.
Consider cylindrical pressure vessel meshed with solid...
Hello everyone!
I’ve seen the following forum thread: https://www.eng-tips.com/viewthread.cfm?qid=310852
but I still have some doubts regarding this quality measure.
1) Most importantly, I can’t find a single universal definition. Even ranges seem to vary a lot depending on the software...
Hello everyone!
I'm working on a simple benchmark problem involving a spring-mass-damper system (for which I can get an analytical solution) modeled like this in Abaqus:
Currently, the damper is represented as modal damping with critical damping fraction for the natural frequency defined in...
Hello everyone!
I'm working on a simple benchmark problem for FEA software. It involves the following simplified model of a bolted joint:
It's not a real bolt, the geometry was made up by me. For now, I only want to test the general procedure.
This FEA model represents half of the whole...
Hello everyone!
I'd like to understand the meaning and practical interpration of complex input and output in harmonic/frequency response FEA.
Let's start with input - each load in this type of analyses can be defined with an imaginary component (F=F_Re+iF_Im). From what I've read, it's...
Hello everyone!
I've seen this thread: https://www.eng-tips.com/viewthread.cfm?qid=495987 and would like to expand the discussion to a more general case. This topic has been puzzling me for some time and seems to be quite common among FEA engineers. And yet I haven't found a comprehensive...
