I echo Dimitris’ response: according to the manual, useCoriolis is TRUE by default so simply adding a line specifying it as TRUE
<div class="">won’t change anything (not sure if that is what you are doing?)</div>

</div>
<div class="">Also helpful is to examine/report the parameter values as dumped in standard output, then you can confirm how they are set.</div>

Maybe it would help to get an answer if you sent a list of what you actually changed in your data files?
<div class="">The before and after. Did you just add explicitly default values?</div>

<div dir="ltr" class="">Hi everyone!<br class="">
<br class="">
I use non-hydrostatic MITgcm model to simulate the propagation of internal waves in three-layer ocean.<br class="">
<br class="">
Now I need to check the impact of Coriolis force to internal waves with it long propagation.<br class="">
<br class="">
I try to enable Corolis force using useCoriols=.TRUE. and f0=1.176E-4 (this corresponds to 54 latitude), but i don't see any influence on my internal wave.<br class="">
<br class="">
What I'm doing wrong?<br class="">
<br class="">
My data file looks like this:<br class="">
