A hands-on week to learn DynEarthSol workflows, discuss geodynamic modeling challenges, and build new tools with the GeoFLAC/DynEarthSol community. Three days of workshops and a two-day hackathon at KIGAM — beginners welcome.
Whether you maintain the code, run simulations, or are simply curious about geodynamic modeling, this is your week. Learn the internals, sharpen your skills, and team up to build something new.
Guided sessions on GeoFLAC/DynEarthSol — from first build to advanced modeling techniques, led by core developers.
Form a team, pick a challenge, and ship. New features, bug fixes, tooling, visualizations — anything that moves the project forward.
Meet the people behind the code. Connect with developers and researchers working on the same problems you are.
GeoFLAC/DynEarthSol developers and anyone interested are welcome — beginners included. No prior contribution required.
DynEarthSol is the open-source code we use throughout the tutorials — a finite element solver for the long-term deformation of Earth's lithosphere in 2D and 3D. Instead of assembling and storing the enormous matrices that traditional implicit methods require, DynEarthSol uses an explicit, matrix-free formulation based on the FLAC algorithm, so it sidesteps the "memory wall" and scales efficiently across CPUs and GPUs.
Solves the momentum equations explicitly with dynamic relaxation — no global matrix assembly, no memory wall as models grow.
A deterministic two-stage summation gives bitwise-reproducible results regardless of execution order, enabling robust GPU acceleration (OpenACC).
Couples tectonics, surface processes (via goSPL), and earthquake-cycle physics (rate-and-state friction) in one 2D/3D framework.
Results, simulations, and visualizations made with DynEarthSol. Participants are welcome to contribute — see how to add yours in the project README.
Days 1–3 are hands-on workshops with tutorials and talks; Days 4–5 are an open hackathon. Sessions run 10:00–17:00 daily, with a one-hour lunch break. The schedule below is tentative and will be finalized closer to the event.
Welcome, project overview, quick environment check, intro tutorials, and opening talks.
Hands-on tutorials on core modeling workflows (inputs, outputs, first models), plus talks.
Advanced tutorials and talks. Hackathon team formation and challenge selection in the late afternoon.
Teams work on their projects with mentor support from core developers.
Final hacking, team presentations, awards, and closing.
* Schedule subject to change. Detailed times will be shared with registered participants. Please bring cash for lunch.
The tutorials are run with DynEarthSol. We'll do a quick environment check on Day 1, but we will not walk through the full build process during the workshop — so please build it on your own laptop beforehand and confirm it runs. This way we can dive straight into modeling.
Clone the DynEarthSol repository (with submodules) and follow the build instructions in its README.
Make sure these are installed before building:
Come with DynEarthSol already built and running on your laptop. Run one of the examples to confirm it works.
⚠️ There is no public Wi-Fi on-site, so download any data, dependencies, and docs you'll need beforehand.
Stuck on the build? Email us before the event so we can help in advance: slee91@kigam.re.kr
The two-day hackathon (Days 4–5) is an open, hands-on sprint to push DynEarthSol forward, guided by the project's 2026 development roadmap. The plan below is tentative and will evolve with participants' interests.
Lightning intro to the roadmap, team formation around tracks, and a community discussion on the GitHub contribution workflow & push policy — then teams start building.
Continued hacking with mentor support, a roadmap & future-direction discussion, then team demos, wrap-up, and next steps.
Bring an idea or join a track on the day. Teams of any size are welcome — solo too. Core developers are on hand to mentor. The goal is working contributions and a shared plan for what comes next.
Accepted presentations from our speakers. Slides and materials are linked where available. Want to present? See the Call for Presentations below.
Share your work with the GeoFLAC/DynEarthSol community. We welcome talks on models, methods, tools, results, and works in progress — from seasoned developers and newcomers alike.
A talk title and a short abstract (150–250 words). Optionally your slides or paper.
Send your title, abstract, and slides (≤ 10 MB) through the form. Large files like videos? Email them to us instead — see below.

This is an in-person event held at KIGAM. There is no online/remote option — join us on-site.
Korea Institute of Geoscience and Mineral Resources

Google Maps is limited in Korea — for directions, Naver Map or KakaoMap work best:
For Korean apps, copy & paste this address:
KIGAM is at 124 Gwahak-ro, Yuseong-gu, Daejeon 34132. Daejeon sits at the center of Korea and is easy to reach by train or bus. Here are the most common routes.
Airport limousine bus — direct to Daejeon (Government Complex / Bus Terminal). ~2.5–3 hrs, ₩26,000–33,000. Tickets at the airport bus counters.
Or by KTX — AREX train to Seoul Station, transfer to KTX to Daejeon Station (~50–65 min).
The closest airport (~1 hr away).
Direct bus to Daejeon Complex Terminal (~1 hr, limited departures).
Or via Osong Station — shuttle to Osong (~20 min), then one KTX stop to Daejeon (~15 min). Taxi ~50 min.
KTX / SRT from Seoul Station or Suseo to Daejeon Station — ~50–60 min. Fastest and most frequent.
Express bus from Seoul to Daejeon Complex Terminal — ~2 hrs.
From Daejeon Station or the bus terminal, KIGAM is ~20–30 min by taxi; from the Yuseong / Government Complex area it's ~10–20 min.
A few tips for international visitors — the right apps and cards make travel much easier.
Google Maps gives limited directions in Korea. Install Naver Map or KakaoMap for reliable walking, transit, and driving routes.
Use the Kakao T app to hail taxis — far easier than flagging one down, and you can pay in the app.
A T-money card works on buses and subways. Buy and top it up with cash at any convenience store (GS25, CU, 7-Eleven). iPhone users can add T-money to Apple Wallet and tap to pay.
A few hotels participants often use. These are suggestions only — please book early, as availability and prices vary.
Business hotel in the Expo/Yuseong area, one of the most convenient options for KIGAM.
Popular full-service hotel in the Yuseong area, near the Yuseong hot-spring district.
Affordable, reliable chain hotel near Government Complex Daejeon subway station.
Travel times and fares are approximate — please check official timetables before departure. For Korean map apps, search: 한국지질자원연구원.
