EuroMPI/USA 2025,keynote by Bob Lucas: The evolutionary flexibility of LS-DYNA
The old codes aren't going away any time soon
- They're solving problems for their users
-- Saving billions of dollars annually
- Backward compatibility preserves decades of investments
-- Including the rich set of libraries and tools they're build on
- They are integrated into bigger workflows
-- E.g., most LS-DYNA input decks are generated by 3rd party tools
--- Cadence ANSA & Siemens Hypermesh
- Generations of engineers know how to use them
- In safety critical fields, regulators insist on continuity
- They are moving targets, constantly evolving, and improving

Concluding Remarks
- There are many codes such as LS-DYNA that have stood the test of time
- They do so by evolving to adapt to new requirements and computing technology
- They leverage an increasingly rich ecosystem of math libraries, compilers, and tools
- OpenMP and MPI are particularly important to science and engineering
- They will be even more so in the future, as the pace of change accelerates
Large Computer-Aided Engineering Applications
keynote by Bob Lucas
LS-DYNA has successfully evolved for four and a half decades.
Today, LS-DYNA embodies over ten million source lines of code, mostly in Fortran, and has many thousands of users worldwide.
