Thank you a lot for answering!

I actually managed to find the problem. The problem was my beta-value of 0.25 in the Newmark integrator. I set the value to 0.3025 instead, and it converged perfectly!

Hi I'm working with kinematic pile-soil interaction problem on my Master Thesis. I have defined a soil column which is 10 by 10 meters (2D, 2DOF) which is connected to a single pile (2D, 3DOF). The contact formulation is defined by zerolength elements with PySimple1-material. I want to model the soi...

Hi, Engin Thanks a lot! I actually figured out the same thing! But now I am certain that this is correct to do! :D I defined 2DOF dummy nodes at the same coordinate as the pile-nodes (3DOF). I then connected the dummy nodes (2DOF) with the soil nodes (2DOF) by using zerolength elements. Finally I de...

Hi I want to couple 2 nodes with a zerolength element which has the uniaxial material PySimple1. The zerolength elements are to couple nodes from quad elements (soil) to beam elements (pile). The problem is that the quad elements are ndm 2 and ndf 2 while the beam elements are ndm 2 and ndf 3. I get...

Hi

Does the PySimple1 material take both tension and compression forces, or just compression forces?

I just want to be sure what I'm doing...

Thanks a lot

Hi! I'm a MSc student doing my Master Thesis this spring. I'm trying to do a free field ground motion analysis in OpenSees, but I'm having some trouble generating the proper input file. I think that I have omitted one or more vital parts in the model building. I have defined the following: - nodes -...
