The OpenSees Community

Hi, Long story short, I am developing a Python wrapper (yet another one) based on OpenSeesPy but with features inspired from FLAC3D (e.g., grouping nodes and elements, retrieving nodes and elements given coordinates...). Among these features, instead of working with tags, I am working directly with ...

Hi all, After reading the following blog post , I have been wondering how to correctly prescribe mass and load for a vertical pipe. In my model, pipes are modeled using force beam elements with a mass of rho * A (rho being the density and A the cross-sectional area). As I understand, I also have to ...

Define the test before the algorithm:

algorithm("NewtonLineSearch") # define type of analysis: time-dependent
test('EnergyIncr',float(1.0e-6), int(100), int(0))

to

test('EnergyIncr',float(1.0e-6), int(100), int(0))
algorithm("NewtonLineSearch") # define type of analysis: time-dependent

Thanks! Yes I used an elastic beam column to setup the model. Fiber sections with a circular patch seems to do the trick.

Hi all, I am fairly new to OpenSEES so there are some things I am not sure how to do in OpenSEES. I'd like to model the bending moment along a vertical steel pipe. To do that, I am modeling the pipes as force beam column elements. I used a simple elastic section for the beam to setup the script, but...
