( *EOS_TABULATED_COMPACTION ) LS-Dyna Error 10246 (KEY+246)

[Pavel Dybskiy]

Hello,

Any idea what is wrong with the following keyword definition.

LSPP wants card#2 in  *EOS_TABULATED_COMPACTION

  Warning - Missing data in Keyword - *EOS_TABULATED_COMPACTION
  Warning occurs in file C:\zz_DYNA_LAPTOP\A_PWA_Pendulum\61_Fr02_SPH_1mm_LC_EOS\Mat_224_SPH_9_EOS_wLC_SDG_2_dlim_1all.k line # 120
 Time to read keyword file =  0.219 seconds

 

LS-Dyna doesn't like beginning of new keyword in the end of curve #31 definition

*** Error 10246 (KEY+246)

    line contains improperly formatted data
     reading *EOS_TABULATED_COMPACTION card.
         At line# 136 of file

Thanks

Often the error occurs before the line numbers provided by LS-DYNA, i.e. it does not realize there is an error until it encounters the next “*” keyword.

 

Looks like it was trying to complete the input for *EOS_TABULATED_COMPACTION and unexpectedly ran into your *DEFINE_CURVE keywords.                         --len

Maybe. 

But, my question is what's wrong in that *EOS_TABULATED_COMPACTION keyword? 

How can I use curves instead of pair of cards? 
Thanks,

Just added 8 empty lines after first card in *EOS, and it is running.

I guess Keyword manual Vol.2 needs correction.

Paul –

 

I assume you can provide 8 blank cards and LS-DYNA will use the *Define_Curve values provided by LCC, LCT and LCK, i.e. the *Define_Curve values over ride those provided on the 8 input cards, blank or not.

 

Check the d3hsp file to see what is echoed for the EOS.  --len

Len,

There is still an issue with EOS definition using curves. 

Empty lines didn't help. 

According to d3hsp they were used by LS-Dyna as 0s.

And curves were ignored.

Hello Paul –

 

I don’t think that finding necessarily disproves that LS-DYNA did not use the curve values, i.e. you input 8 lines of zero and the d3hsp file echoed those 8 lines.

 

I think you need to compare the results of two runs:

1\ using 8 lines of zeros and the curves

2\ 8 lines with the same values but no curves.

 

If the results are the same, then in run 1\ LS-DYNA is using the curves.

[P.D.]

Len, 

In my previous runs for this model I was using EOS-polynomial-compaction with 8 lines format.

It was all right. Now, I thought to use curves for convenience . I tried various combinations, including what you have suggested. I tried ascending and descending abscissa values. All combinations except my original produced garbage results. 

What else can be done to troubleshoot this issue?

Thanks,

What version of LS-DYN are you using?

If it is not a recent version you might try R14.

Else I think you need to ask Support for help on this apparent bug.
