Sensor Definitions in LS-DYNA
Published by May 18th, 2010 in LS-DYNA Bytes and LS-DYNA Output. 0 CommentsEnergy Output to D3PLOT Files
Published by October 3rd, 2007 in LS-DYNA Bytes and LS-DYNA Output. 0 CommentsSeveral options exist in LS-DYNA to output the energies, stress and strain information for shells, solids and beams depending on the choice of parameters in *DATABASE_EXTENT_BINARY keyword. These are important to understand and enable proper postprocessing of the results when using any post-processors to read in D3PLOT. It must also be noted that increased output [...]
Starting 971, LS-DYNA allows the direct input of the physical accelerometer mass in the *ELEMENT_SEATBELT_ACCELEROMETER keyword which is lumped equally to the three nodes that is used in defining the accelerometer. This eliminates the need to create additional *ELEMENT_MASS keywords to account for the physical accelerometer mass.
Nodal Time History in Local Coordinate System
Published by October 2nd, 2007 in LS-DYNA Bytes and LS-DYNA Output. 0 CommentsIn several simulations, the response of a nodal point (displacement, velocity, and acceleration) is helpful to be output in a user-defined local coordinate sytem. LS-DYNA offers several options to enable the local system output of nodal time history data and here are some examples of it. All nodal time history data is output to either [...]
Principal Stress Calculator for Shell Elements in DYNAIN File
Published by August 1st, 2007 in LS-DYNA Bytes and LS-DYNA Output. 3 CommentsRecently, there was a request to ouput the principal stresses for each element at lower and upper surfaces of each shell element in DYNAIN file to use in some failure theories. I beleive this feature is a routine output in PamStamp simulations. To enable this, the attached ‘C’ code can be used that reads in [...]
Monitoring Incremental Elapsed Time as a Function of Simulation Time
Published by December 4th, 2006 in LS-DYNA Bytes and LS-DYNA Output. 2 CommentsWhen running explicit simulations in LS-DYNA, it is very important to understand the total CPU clock and the total Elapsed time used by the solver. This information is available at the bottom of every D3HSP file written by LS-DYNA as shown below. The total elapsed time reported in the file is the difference between the [...]
