How do I work around fatal message 4647?

ThorPaulli over 6 years ago

I get the following fatal message around 20 design iterations into a topology optimization problem of a large system:

USER FATAL MESSAGE 4647 (TIMCHK)

INSUFFICIENT TIME TO COMPLETE DFNSB

CPU ESTIMATE =271 SEC. CPU REMAINING =198 SEC.

I/O ESTIMATE =1302 SEC. I/O REMAINING =99999999 SEC.

I assume it's due to the I/O remaining time, but why does this appear - and how do I work around it to have my solution converge properly?

Thanks a lot!

Thanks for your reply, Sanjay. I saw I had the "all" write option enables for displacement, stress and SPC forces, so the f06 file would grow to a ridiculous size. That may have been the problem. I'm runinng it again without the write option to see.
