OpenSees: New Release and More

The OpenSees Development Team has been very busy! Take a look at their recent updates below.

OpenSees Version 2.4.0 has been released

Version 2.4.0 includes new options to perform thermo-mechanical analysis. In addition there are new materials for:
a) the continuum modeling of concrete structures,
b) the continuum modeling of large post liquefaction of sands,
c) new deterioration models for lumped plasticity modeling.

There are also a number of new elements for:
a) modeling of Triple Friction Pendulum's,
b) stabilized single point integration elements for use in continuum modeling,
c) beam to node contact elements.

The full list of additions/modifications can be seen at:

For those interested in parallel processing:
a) We are making Windows binaries again available at the download page.
b) The binaries are available through the OpenSeesLab tool on NEEShub. NEEShub allows you to run OpenSees parallel scripts on the NSF XSEDE resources of Ranger, Steele and Hansen (4096, 4232, and 96 processors respectively being available to NEEShub users).

OpenSees On the Road

Next year we will hold a number of mini OpenSees Days workshops around the country. We are looking for venues. So if anyone would like to propose their own institution, please email Frank McKenna.
