Curious behaviour with tide

Dear all,

I’ve got a problem with tides in my simulation. I noticed a curious behavior happening every midnight. A “waves” appears on each open boundaries of the domain exactly at 00:00 every days.

See the two pictures attached

Does anyone meet this behavior before ?

Regards

Dear all,

I finally resolve. The mistake was the cppdefs.h keys TIDES_MAS wihch xas activated and should be not in my case.

Regards
