Dear All,
I am using the ANSYS version of LS Dyna and it appears that they have combined MAT_054/055. I have entered the data but I get the following error.
*** Error 10141 (KEY+141)
     Load curve id 1347569219 is undefined
 
 *** Error 10141 (KEY+141)

I do not see a load curve reference in the Keyword card. Any help is highly appreciated.

best wishes,
Ganesh
