Hi Kundar,
Thanks for the email. The problem could well be a memory leak. Check
that you are not creating
Variable objects within a loop. Sometimes, recursive creation of
Variables can be problematic, but the
error message would be a little different. Still worth checking
though. Also, run with the viewers turned off.
I've experienced memory leak issues with some of the viewers. When
you run the code, check to see the
memory usage with "top" or something else. It should then be clear
whether there is a leak.
Hope the above helps.

Hello all,
I got a technical problem while I ran fipy to solve Cahn-Hilliard
equation. The elements is 30625 and dt=1. When the program ran at
step 844, it terminates with the error message:

May someone know what's problem, and how can I fix it?
Thanks and Regards,
