Tidal current TPXO for open sea 8 years 7 months ago #21014

hello,

I'm working with telemac2d version v7pr0 for setup a hydrodynamic model for the French Caribbean islands.
For now, i just want to imposed the tidal forces from TOPEX (ocean-circulation with HYCOM and wind, later). I have imposed for all my boundaries conditions 5 6 6 . For avoid that my model be over constrained, i use the Thompson boundary option.
But the results give me a lot of instability and wrong tidal signal. I don't know how increase this, i need some advice from the TELEMAC community.

Thanks in advance for yours advices

c.coulet OFFLINE Moderator Posts: 3722 Thank you received: 1031	It look likes you have some problems with the boundary conditions... Try to start only with the water level (without velocity). Regards

j.dasilva	Thank you Mr coulet indeed it was my BC and more precisely the Thompson boundary option who generated wrong values. Regards
