Ansys LS-DYNA Student, Windows x64<\/p>\n<\/li>\n
SMP double precision R16.1-180-gd50332dbe5, one thread<\/p>\n<\/li>\n
Units: mm-ms-g-N-MPa<\/p>\n<\/li>\n
2D axisymmetric S-ALE, 12,423 cells<\/p>\n<\/li>\n
808 cells initially filled with EMULSION<\/p>\n<\/li>\n
*MAT_HIGH_EXPLOSIVE_BURN (MAT_008, BETA=0) with *EOS_JWL<\/p>\n<\/li>\n
NEIPH=4, D3SALE=0, DMPMSH=1<\/p>\n<\/li>\n
Termination time: 0.100 ms<\/p>\n<\/li>\n<\/ul>\n
I compared two input decks that are identical except for the lighting time LT in *INITIAL_DETONATION:<\/p>\n

v3: LT=0.0 ms
Normal termination, but the maximum absolute total-energy drift calculated from all original GLSTAT states is 15.995852%.<\/p>\n<\/li>\n - \n
E2: LT=0.200 ms, after the 0.100 ms termination time
Normal termination, and the maximum absolute total-energy drift is only 0.00049064%.<\/p>\n<\/li>\n<\/ol>\nNo interpolation, state deletion, filling, smoothing or renormalization was used.<\/p>\n
However, I cannot yet prove from the original output that burn fraction F remained zero in all 808 explosive cells in E2. The binout contains only nine tracers, and the R16.1 manuals do not identify the exact full-field burn-fraction mapping for 2D axisymmetric S-ALE.<\/p>\n
Could an LS-DYNA specialist please clarify:<\/p>\n

With D3SALE=0, where exactly is the per-S-ALE-cell MAT_008\/JWL burn fraction F stored in d3plot? Please identify the documented array\/record location and the LS-PrePost Fcomp or Misc component.<\/p>\n<\/li>\n
- \n
With D3SALE=1, what is the corresponding LSDA path and array name in d3sale?<\/p>\n<\/li>\n
- \n
Is NEIPH=4 sufficient for full-field burn-fraction output for MAT_008 + EOS_JWL in 2D axisymmetric S-ALE? Does HISNOUT=3 provide valid labels for this field?<\/p>\n<\/li>\n
- \n
Are these output fields identical between the R16.1 Student and commercial executables?<\/p>\n<\/li>\n
- \n
Is the approximately 16% energy loss for LT=0, compared with approximately 0.00049% for LT=0.200 ms, a known R16.1 limitation, defect or energy-accounting behavior? Is there a recommended patch level, diagnostic output or control setting?<\/p>\n<\/li>\n<\/ol>\n
I am not claiming that the A\/B comparison uniquely proves that burn, JWL or advection is the cause. I first need the officially supported full-field burn-fraction mapping.<\/p>\n
Thank you.
