<div style="margin: 0cm; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">I am Juncheng, one of PhD student in University of Toronto, and I am trying to run a tutorial simulation with MITgcm, for example the Baroclinic_ocean_gyre,
however, I had several questions:<o:p></o:p></span></div>
<ul type="disc" style="margin-bottom: 0cm; margin-top: 0cm;">
<li class="MsoListParagraph" style="margin: 0cm; font-size: 12pt; font-family: Aptos, sans-serif;">
<span style="font-size: 11pt;">I want to change the grid numbers, I try to change the grid parameters in SIZE.h and data files, when I run the simulation, I had some error which is related to the bathy.bin file due to the changed grids. I am wondering what
is a good way to change the grid numbers.<o:p></o:p></span></li><li class="MsoListParagraph" style="margin: 0cm; font-size: 12pt; font-family: Aptos, sans-serif;">
<span style="font-size: 11pt;">I try to open the bathy.bin file in Jupyter Notebook, however, it can not be opened,<o:p></o:p></span></li></ul>
<div style="margin: 0cm 0cm 0cm 36pt; font-size: 12pt; font-family: Aptos, sans-serif;">
<span style="font-size: 11pt;">Error: bathy.bin is not UTF-8 encoded saving disabled. See console for more details<o:p></o:p></span></div>

<li class="MsoListParagraph" style="margin: 0cm; font-size: 12pt; font-family: Aptos, sans-serif;">
<span style="font-size: 11pt;">I am also curious about if I want to change the bottom topography, what should I do to modify it.<o:p></o:p></span></li></ul>
<div style="margin: 0cm; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">I hope you can give me some advice to solve the issues.<o:p></o:p></span></div>
