Although a fix was implemented that improved the performance in idealised test cases the performance in realistic simulations (e.g. ORCA025) is worse. It is not clear that the new or old formulation is correct for the case of sloping bathymetry and partial steps. 182 183 183 [[BR]] ''' Status: ''' [[BR]] ''' Main Tasks: ''' [[BR]] ''' Science Reviewer:''' [[BR]] ''' System Reviewer:''' [[BR]] ''' Deadline:''' [[BR]] ''' Priority:''' [[BR]] ''' Depends on:'''[[BR]]184 [[BR]] ''' Status: ''' [[BR]] ''' Main Tasks: ''' [[BR]] ''' Science Reviewer:''' [[BR]] ''' System Reviewer:''' [[BR]] ''' Deadline:''' [[BR]] ''' Priority:''' [[BR]] ''' Depends on:''' [[BR]] 184 185 185 186 '''ROBUSTNESS-3 / CNRS - Academic test cases in the system''' … … 201 202 (2) Revisit the SMS models distributed in the model ( AGE tracer, Natural C14 vs Bomb C14, etc ...)
