Dear Fipy developers and users,
I would like to split 4th-order DiffusionTerm into two 2nd-order. Taking
the "examples.cahnHilliard.mesh2DCoupled" as example.
_http://www.ctcms.nist.gov/fipy/examples/cahnHilliard/generated/examples.cahnHilliard.mesh2DCoupled.html_
When running this example, I cannot get expected result as shown in the
web. Instead, the \phi will diffuse out to 0.5. So, is there anything
wrong with the code?If the splitting method is correct? Thanks.
Regards
Ronghai
