[mesa-users] MESA test suite case - wd_ignite

[Francis Timmes]

1) say what you are trying to accomplish. 
2) send your complete inlist(s) so someone could try to replicate issue.
3) say what version of mesa you are using.

until you complete these three items, there is not enough 
information on the table to help you.
