I’m a PhD student with a background in renewable energy systems, now working on underground hydrogen storage in salt caverns. My main research objective is to quantify frequency‑dependent thermo‑mechanical damage over ~30 years for high‑frequency hydrogen injection/withdrawal (≈30–50 cycles/year), and derive a safe operating frequency envelope.
I’m considering OpenGeoSys as my primary tool to build investigate my research objective
I’d like to ask:
- Is OpenGeoSys mature enough for long‑term THM simulations with creep and damage in salt rock at cavern scale (hundreds of meters, 30‑year time horizon)?
- Are there existing examples or benchmarks close to this use case (salt caverns, deep repositories, or similar rock mechanics problems) that you’d recommend as starting points?
- From your experience, what are the main numerical or workflow pitfall (e.g., mesh design, time stepping, convergence, material model choices) for this type of problem in OGS?
- I am not a geophysicist. Considering my background do you think its feasible in to achieve this research objective in next 2 years?
Any pointers to example projects, publications or input files would be extremely helpful.
Thanks in advance for your insights and for the work on OpenGeoSys.
