Welcome to the June 2026 edition of OpenSees Digital Digest, a monthly summary of content published at OpenSees Digital.
Verification and correctness of structural analyses continue as recurring themes this month.
- Something They Can Agree On – Demonstrates one of the few cases where displacement-based and force-based elements give the same material nonlinear flexural response.
- A Strong Response – Explores the sound of silence in drabble form.
- Assertions of Failure – Shows that assertions on expected failures are just as valuable as assertions on successful analyses.
- The Worst that Could Happen – Emphasizes the importance of warning messages when the analysis could give physically meaningless results.
- Reinforced Concrete Column Buckling – Provides a minimal working example for column buckling using fiber sections in a corotational mesh of frame elements.
- An OpenSees Manometer – Verifies the PFEM in OpenSees can solve a multi-fluid hydrostatic problem.
Next month, look for more posts on structural and fluid verification, as well as whatever queries or perplexing analyses come up with OpenSees.
OpenSees Digital Rewind
From June 2021, five years ago this month.
- There’s Three, Actually – Compares the mixed beam-column element formulation to the more familiar displacement-based and force-based formulations.
Thanks for reading, and see you next month!
