【讨论】How to run ls-dyna file in ansys?

gzchen

Dear friend,
  
I want to make the model in FEMB and run it in ansys/lsdyna.
I hope you can show me how to do it in detail.
  
Thank you

easy
after you finish the model by FEMB
ouput the .k or .dyn file, it can be open as txt files
find the key word  
*DATABASE_FORMAT
                     0
change the value 0 to 1 or 2
value 1 means for ANSYS only results files, 2 for ANSYS and LS-DYNA results files
  
then u can submit the .dyn or .k file by ansys/lsdyna
use its tool "LS-DYNA Solver "
or just use command in DOS
like this:
lsdynaxx i = jobname.k pr = product name  
for example:
lsdyna70 i=crashtest.k pr=ansysds
  
u can search the directory
[your ansys directory]\Ansys Inc\v70\ANSYS\bin\
to find the ls**.exe file
in my directory, ansys V70, the file is ls960.exe
so the exact example is:
  
ls960 i=crashtest.k pr=ansysds
  
u r welcome

Hi, IIS23,
  
Thank you for your help.
I am using ansys 8.0, it is better.
  
Thanks anyway.

不论你是用ANSYS8.0还是其它的版本，LLS23的方法都是适用的。因为它从最初的版本来。从ANSYS7.1后就专门有一个LS-DYNA SOLVER 了。其实在ANSYS5.7的时候就不用到DOS状态下去算了，有专门的WINDOWS版。只不过你的ANSYS8.0里用的是LS970，而别人用的是LS960而已。
