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:
Traceback (most recent call last):

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