Changeset 8907 for branches/UKMO

Timestamp:

Author:

Message:

Modified implicit bfriciton to only be done in WAD cases
This aids bit comparison tests to show WAD code does not effect CONFIGS,
unless you want implicit bfriction.

Location:

Files:

• dynspg_ts.F90 (modified) (2 diffs)
• wet_dry.F90 (modified) (2 diffs)
