Dear All,

I'd like to know your advise on the following problem:

I'd like to model the behaviour of steel column to steel beam joints using a phenomenological model. I'm using connector elements to do this, namely UNIVERSAl and JOIN connectors.

In the connector behaviour I'd like to model the non-linear behaviour of the joint considering the loading, unloading and reloading (in the opposite directions, stress sign). The loading and reloading curves are different.

Using  *CONNECTOR ELASTICITY, COMPONENT=XXX, NONLINEAR is not a solution since the connector is elastic so it unloads with the same stiffness as it loads.

Hi All!

My problem is quite simple:
I need to change (add arguments) to a inp file, then submit the inp file
for analysis and finally to
read some results from the odb file.

I choose to use python (not the PDE provided by abaqus CAE but the
general python GUI). I’m sure this choice has consequences, perhaps the
import abaqus won’t work? This could bypassed if I run my code using abaqus python in the command window.

To add arguments to the inp file using python is easy, however I’m
struggling to find how to submit the inp file for analysis (w/o going to
CAE), maybe:

import os
os.system('abaqus job=file_name interactive double cpus=2')
