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 [...]

Published by July 29th, 2010 in LS-DYNA Bytes and d3View Features. 0 CommentsUnderstanding the rate of convergence when employing Explicit Dynamic Relaxation can be very useful to track model sensitivity and to solve convergence problems. d3VIEW now has support to auto-extract the convergence information after a simulation is completed. It also processes DR graphics data to identify points of divergence. Attached is a snapshot from a recent [...]

Sensor Definitions in LS-DYNA
Published by May 18th, 2010 in LS-DYNA Bytes and LS-DYNA Output. 0 CommentsSensors can be used to trigger entities based on certain criteria. The following image is a high-level steps involved to take advantage of sensors in LS-DYNA.
*RIGIDWALL_{DISPLAY} option
Published by May 3rd, 2010 in LS-DYNA Bytes and LS-DYNA Elements. 0 CommentsRigidwalls are analytical representations of surfaces or volumes that are frequently used to represent stiff structures that are either stationary or in motion. Viewing of such analytical definitions in D3PLOTs were not possible for most rigidwalls. A new option in LS-DYNA named DISPLAY that can now be used to any *RIGIDWALL definitions which causes LS-DYNA [...]
