HM Output Settings LS-Dyna

Recommended Posts

Hi,

 

I recently started to use Hypermesh 2017.2 as a Preprocessor for LS-Dyna. I'm already quite satisfied with the usability besides one exception: since we're using LSPrepost for the model creation as well, which is providing a clean and structured output regarding the keywords, Hypermesh doesn't:

 

LSPrepost:

*MAT_PIECEWISE_LINEAR_PLASTICITY_TITLE
ALUMINUM PURE 99.45-O CONDITION
$#     mid        ro         e        pr      sigy      etan      fail      tdel
         12.71300E-6     68948      0.33  0.013362       0.0    0.2723       0.0
$#       c         p      lcss      lcsr        vp       lcf   
       0.0       0.0         3         0       0.0         0
$#    eps1      eps2      eps3      eps4      eps5      eps6      eps7      eps8
       0.0       0.0       0.0       0.0       0.0       0.0       0.0       0.0
$#     es1       es2       es3       es4       es5       es6       es7       es8
       0.0       0.0       0.0       0.0       0.0       0.0       0.0       0.0

 

HM:

*MAT_PIECEWISE_LINEAR_PLASTICITY_TITLE
ALUMINUM PURE 99.45-O CONDITION                                                 
         12.7130E-06   68948.0      0.33  0.013362       0.0    0.2723       0.0
       0.0       0.0         3         0       0.0
$$ HM Entries in Stress-Strain Curve =         8
       0.0       0.0       0.0       0.0       0.0       0.0       0.0       0.0
       0.0       0.0       0.0       0.0       0.0       0.0       0.0       0.0

 

I also attached the original and HM output file to point out the difference.

As far as I see, I'm not using very fancy keywords that HM should be able to process and which it's doing for the *DATABASE and *CONTROL keywords. Are there any setting options I missed? Or do I need an add-on to receive clean keyword output throughout the whole file?

 

Thanks in advance for your support.

 

Regards

Hi @christian_pohl

 

It is a known issue that HM doesn't maintain comment during export. if the incoming file has the comments then in most cases its maintained, but not guaranteed.

 

Our development team is working on the same.
