Last change on this file since 5394 was 1793, checked in by Ehouarn Millour, 11 years ago

Improved sponge layer:

  • Sponge tendencies are now computed analytically, instead than using a Forward Euler approximation.
  • Sponge tendencies are added within top_bound, and the sponge is applied after physics tendencies have been taken into account.

These changes imply that GCM results (when using sponge layer) will be differentwrt bench test cases using previous revisions.
