APDL slows down

thread1630-500426

APDL slows down

APDL slows down

(OP)
Hi everyone,

I have the following problem:
When I start a calculation with ANSYS APDL from some code, it starts quite quick and slows down a little bit while calculating. I see that at the speed in which it reads some scalar parameters / the speed in which the read scalar parameter are printed in the output window. Then, when the calculation finishes I use the

CODE --> apdl

/clear
command and execute the same codeagain. But the calculation time nearly double up to the first time for the exact same code. When I repeat this again, the needed calculation time increases again. But when I close APDL and open it up again. The calculation time decreased to the initial value. Can anyone explain why the program slows down so drasticly? I would be very thankful for any help.

Thanks in Advance!

RE: APDL slows down

Look to see if the memory being used by ANSYS is going up each time. It might be doing a poor job of releasing memory and instead of being all in RAM it's going to external storage which is slowing it up. When you quit ANSYS the operating system releases all the memory and starts fresh.

RE: APDL slows down

I have tested it and the used RAM does not increase while running the code. Any other thoughts?
