Hello,
I am running a random analysis on a big model and i believe the prepossecing has been done correctly (first Rnd.An on Optistruct). But apperently it hasn't and i am unable to understand the following error message:
*** INTERNAL PROGRAMMING ERROR # 251 ***
Specified vectors (717 - 717) out of range (1-716).
What is it talking about exactly so i could go and check it?
Thanks
PS: share fem file. output if needed
I would suggest you to get in touch with your local hyperworks support for this error.
