During MPP LS-DYNA execution, often there is a need to know how each of the “threads” are doing in terms of overal CPU utilization. Until now, one has to wait till the job is fully finished so we can review the load-balance information from the main D3HSP file. From LS-DYNA 971 r7 onwards, there is…

Recently held 12th LS-DYNA Conference, June 4-5 2012, was a huge success with over 680 attendees from over 21 different countries. It was great to see users from all over the world attend and present some fascinating work in LS-DYNA. The concluding talk on LS-DYNA developments and roadmap from Dr. John Hallquist and the development…

Stress Triaxiality is the ratio of Hydrostatic stress and the von-Mises stress and is known to have a great influence on the plastic deformation. You can view this factor in LS-PrePost now as shown below.

Its been a while since my last post. I wanted to take the time to share that I will be teaching an LS-DYNA Class in Detroit, Michigan. You can visit Registration for more information. FEA Information will be including more information on this in its next publication.

I will be attending the upcoming LS-DYNA Update meeting in Pune (May 3, 2011) and Bangalore (May 5, 2011). You can find more information at LS-DYNA Update meeting . If you are in Pune or Bangalore, it will be great to see you there.

With the recent growth of multi-core chips, scalibility of pure MPP LS-DYNA beyond 128 cores has shown degration due to several factors including latency and network communications. LSTC has recently developed a new code named “Hybrid LS-DYNA” that provides sustained scalibility for large number of cores and also yields digit-2-digit repeatibility when changing the number…

Over six months ago, two students, Rob Moncur, pursuing his MS, and Satyan Chandra, pursuing his UnderGraduate Studies, in Brigham Young University (BYU) set out on a path to build a LS-DYNA crash-analysis model of the PACE F1 car in under 8 weeks. Under the guidance of their professor, Dr. Greg Jensen, and with minimum…
