It has been very busy weeks, turning into busy months and without noticing, almost a year has passed. The main news is that I got a Academy of Finland project, Compact It, and we still are looking for a researcher who would be interested to take part. Your task will be to use and develop Granular Material Point Method and Uintah software suite, to model dynamic soil exchange. The project will involve close cooperation with Menard and build over resaerch from 2013. You can find the advertisement at Aalto webpage. The position is open until filled. Please apply, I try to check the applications weekly!
Geomeasure project awarded
Would you like to contribute to GEOMEASURE? We are looking for a postdoctoral researcher who would use MPM to model offshore in-situ tests!
Academy of Finland has awarded Aalto & Geological Survey Finland consortium financing for the Geomeasure project. We will investigate the Finnish seabed with GTK research vessel Geomari and find new ways to interpret the results of the tests, in particular free fall penetrometer tests. To do that, we will take samples from the seabed and correlate results of experimental testing with the penetrometer data. Also, the tests will be numerically modelled with MPM. We also plan to investigate the behaviour of the deposits under cyclic loading, typical for wind turbines.
Review Paper on Material Point Method
Our review paper on Material Point Method is now available here. The link will expire in a month, but I hope that by that time we will be able to provide a copy that could be used instead.
Please have a look, and let me thank all the co-authors: professors Martin Berzins, Will Coombs, Jim Guilkey, Matthias Möller and Kenichi Soga, as well as the doctoral students (some of whom graduated by now): , Tito Adibaskoro, Seyedmohammadjavad Seyedan, Roel Tielen and Quoc Anh Tran (all the names in alphabetical order). Thank you again!
We got new paper published on Granular Material Point Method in Computers & Structures. We are proud of the paper, where we show how you can get continuous material discontinuous during the flow, and then, continuous again. Thanks to that, we can have the silo filled properly 🙂
Are you interested? We have open positions for a post-doctoral position, open until 14th of June 2021. Contact me for more information, as you will have to show your multidisciplinary approach in the application. Good luck!
E-Unsat 2020 presentation and Young Invited Lecture
The E-Unsat 2020 has been excellently organised and a resound success, despite being fully online. Even though I must say I did miss the chats with friends and informal, but often illuminating discussions with the attendees, I still have seen many great presentations and learnt much.
I was also presenting the paper authored by Dr Abed and me on validation of gas transport couplings in our THMC coupled Finite Element Method code Thebes (presentation here, and paper here). We have much more to do in relation to gas transport – my doctoral student Abhishek Gupta is responsible for that, and we hope to deliver ambitious simulations of gas transport of a generic nuclear waste repository in a year or two.
I was delighted to deliver the Young Invited Lecture on Granular Material Point Method, something we are working on with Seyed Mohammad Javad Seyedan. We will aim to publish full paper based on the presentation, but for now, the presentation is here.
Many more exciting things has happened and is happening with the research in my group – I will try to update you on that soon!
MPM 2019 Conference in Cambridge and presentation at Imperial College London
We have attended the 2019 MPM conference in Cambridge in numbers. I had a presentation on Uintah software and a keynote, while other members of the research group presented their research. You can find the proceedings here: http://mpm2019.eu/papers
In particular there are some presentations available:
- Keynote “Accuracy, errors and convergence of MPM”
- Uintah software presentation (100 MB, external link)
- MPM Simulation of fine particle migration process within unsaturated soils presented by Dr Xiaoqin Lei
- Continuum modelling of the granular flows in gaseous states using material point method, presented by SeyedMohammadJavad Seyedan
And the conference papers:
- MPM Simulation of fine particle migration process within unsaturated soils (Lei & Sołowski)
- Continuum modelling of the granular flows in gaseous states using material point method (Seyedan & Sołowski)
- An improved moving least squares method for the Material Point Method (Tran, Berzins & Sołowski)
- Moving least squares reconstruction for B-spline Material Point Method (Tran, Wobbes, et al.)
On the way back, I have been given opportunity to present my research at Imperial College London. In particular, you can download the abridged presentation related to our research with Dr Abed in project THEBES: THMC Behaviour of the Swelling Clay Barriers
