The Eurasian OpenSees days 2022 conference was a lot of fun! Especially because I had the opportunity to go with two students: Omar Oyarce and Alberto Hurtado (shown in the picture above with professor Pedro Arduino from University of Washington, Seattle) and show them what this little academic niche is all about.


Also, I had the honor of being invited to give a keynote lecture! This is my first one, and I really hope I could get some of my research ideas across, despite taking to much of my audiences tme. I talked about my current research grant objectives and how some new available tools in OpenSees (and the jungle around OpenSees), together with my new HPC cluster make it possible. Here is a pic from the keynote. I'd like to reiterate and make public my gratitude towards the organizers for selecting me for this.


I also gave a talk on my former student Felipe Elgueta's implementation of isogeometric analysis of shells in OpenSees and his thesis work.


We got to hang out with well established professors such as Enrico Spacone, Guido Camata, and Pedro Arduino.

And also meet the new, rising stars in the OpenSees world: Davide Gorini, Fabio Di Trapani, Cristoforo Demartino, Tony Fierro, to name a few but leaving out so many. See the list at the bottom of this article for a more complete appreciation list.

OpenSees is really going in different, new exciting directions, as can be seen from the breath of the subjects covered in the conference. Striking new directions include metamaterial modeling and molecular dynamics. But also there is a lot going on in more classic study areas such as soil-structure interaction modeling (still no dogmas on SSI modeling I'm afraid... more research is needed) and structural mechanics. Not a lot of soil modeling going on (outside SSI) in the conference, I know there is some new stuff (geotechs should get their stuff together!). AI is entering the OpenSees stage with a lot of strength. It's cool to see all the new tools surrounding OpenSees which people are coming up with (visualizers, python interfaces, site response analysis aids, you name it!). The big star is STKO from ASDEA group, that has reached an amazing level of maturisty since last OpenSees days conference at Porto, Portugal. A lot of new research is being powered by STKO, with stunning visuals, and its good to see all the open contributions to OpenSees coming from that team.

I was impressed by a few talks and I hope to hear more from the authors. Here are some in no particular order (the order of the program):
