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. 204 204 205 [[BR]] ''' Status: ''' [[BR]] ''' Main Tasks: ''' [[BR]] ''' Science ''' Pre-viewer''' :''' [[BR]] ''' System ''' Pre-viewer''' :''' [[BR]] ''' Deadline:''' [[BR]] ''' Priority:''' [[BR]] ''' Depends on:'''[[BR]]205 [[BR]] ''' Status: ''' [[BR]] ''' Main Tasks: ''' [[BR]] ''' Science ''' Pre-viewer''' :''' [[BR]] ''' System ''' Pre-viewer''' :''' [[BR]] ''' Deadline:''' [[BR]] ''' Priority:''' [[BR]] ''' Depends on:''' [[BR]] 206 206 207 207 '''ROBUSTNESS-3 / CNRS - Academic test cases in the system'''
