Large deformations with soil analysis

Hi, I'm running soil analysis using 2D quad elements with PressureIndependMultiYield material. The peak shear strain is set at 0.1. I was wondering, what is the limit of deformation above which the model is no longer valid ? Is it relevant to simulate large deformations with this model ? Thank you f...

simple question about the print command

Hi, I'm performing a transient analysis and I would like to visualize the results on GID (i.e. generating an output file with a similar structure than a *.flavia.res). In order to do that, I'd like to use the print command and print the displacements at each node of model, for each time step. The pr...

Hi,

It works ok now (I've replaced constraints Plain by constraints Transformation): I just hadn't noticed that this method required homogeneous single-point constraints.

thx anyway,

Pierre

Imposing a biaxial displacement

Hi, I am using a soil model (2D quad elements with PressureIndependMultiYield behavior) and I need to impose a progressive displacement on a given node. The direction of the displacement needs to follow both directions (x and y). I have tried to create two differents load patterns, using the sp comm...
