Livermore Software and Technology Company (LSTC), Livermore, CA has recently released LS-DYNA R11.0.0. This release is ready-to-use and is our baseline at Predictive for implicit and explicit work. It is stable and is not a classic xx.0.0 release as is common in the software industry.
Let me explain why: LSTC’s is very transparent about how it develops LS-DYNA and any published release (see release notes.)
So what does this really mean? A released LS-DYNA version is not a “fresh, hot-out-of-the-developers-oven” version of the code. It has gone through months and months, if not years of bug fixes by the development team and user community. The process is quite rigorous, for example, once the LSTC team decides enough-is-enough, a branch is somewhat sealed off from any new major code changes (i.e., R11.xxxxx). While this branch is static, the Development Team continues code development under the designation of Dev_XXXXXX. As the code is fine-tuned and bugs removed, applicable updates are made to the branch and if applicable to prior released versions of the code. At this stage, if the code is deemed ready by the Team, it is run through a suite of verification problems and released to the simulation community. One will note that through-out this whole process, there is no VP of marketing or sales pushing the team to release, it is only released when it is right.
Why LS-DYNA R11.0.0?
- Big jump in implicit analysis capabilities;
- Advanced multi-threaded implicit solver;
- New element formulations for implicit;
- General, all around faster and better.
