That is what your data.obcs shows….if that is true that is why your currents look poor. The open boundaries are vital to get correct for your domain as oscar shows you have a strong through flow</div><div class=""><br class=""></div><div class="">3) you really should make the bathymetry flat in the open boundary restoring region. Otherwise prescribing normal velocity is equivalent to prescribing vertical velocity as well, via divergence, and you don’t want spurious vertical velocity</div><div class=""><br class=""></div><div class="">4) I prefer to set tangential velocity to zero on the boundary, otherwise you do need to prescribe a divergence somewhere….Also setting tangential = 0 damps waves</div><div class=""><br class=""></div><div class="">-Matt</div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jul 8, 2020, at 9:06 PM, Dimitris Menemenlis <<a href="mailto:dmenemenlis@gmail.com" class="">dmenemenlis@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html; charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">Hi Kunal, impressive start!<div class=""><br class=""></div><div class="">It’s best if you keep discussion in MITgcm-support, however,</div><div class="">that way other MITgcm users might contribute to or benefit from the discussion.</div><div class=""><br class=""></div><div class="">So you have no river runoff?
