Hi,
I have the following problem. I start a small symetric model which I analyse in static mode. Everything is stable, convergence is very good.
I then switch to dynamic analysis, without adding anything (no force, no mass, nothing).
The system is very simple, as shown in the picture. It consist...
Hi,
I am conducting a displacement controlled analysis.
In a first attempt, I ran 30 000 steps for a 0.1 displacement total ( that make 0.1 / 30 000 displacement per steps).
Then it failed at around 28800.
I said fine, I'll just increase the number of step, to, say 35 000. There I thought I had...
Hi,
I would like cue on a issue I have with my FE model. I do model (or try ot) the ultime bearing capacity of a footing resting on a purely frictionnal soils (I do take account the weight of the soil). I use quad element to mesh to soil. The stress-strain rel. is a Drucker-Prager. I did use...
Hi,
I am modelling a soil deposit using quadElement. I use a ElasticIsotropic material for the moment. I define a grid 10x10 (meters) with meshing at 1 m in both directions. I assign mass to the element in their vertical direction to simulate gravity effect and I plots the results using R (you...
Hi,
I am trying to create a soil model to conduct a total stress analysis. I use Opensees to do so.
I would like to know if my model constraints looks okay. I have a number of convergence issue and I wonder if those are due to my model being ill defined.
The model have loop that iterate to...
Hi, I am new to the forum so if I post the question in the wrong section excuse me!
I am a new user to the finite element method and I am learning by myself so please don't get offended if my question seem a little stupid... there is much to learn on the FE subject.
Right now, am using the...
