Hi all!
Using ROMSTOOLS, I'm doing a simulation in a region where the coastline has an angle of about 45° to the north-south axis.
By default, ROMSTOOLS generates grids in a square domain with sides parallel and perpendicular (90º) to the north-south axis (correspondingly).
But I want to make a grid parallel to the coastline axis, not to the north-south axis; this means I need to rotate the grid in order to fix it according to coastline.
In the uploaded picture there is the default grid and domain; the green rectangle represents the orientation of the grid and domain I would like to have.
¿Can you help me to change the grid orientation, please?
Thanks in advance!!!!

Re: Grid orientation with ROMSTOOLS
Something like this? This is obtained using a rotated Mercator projection. As a result the grid has the smallest possible ratio between maximum and minimum grid spacing (1.012 for this example).

Exactly nmolem!
I would like my grid and domain look like the picture you uploaded.
But how can I do that; which part of the code do I have to modify?
I'm newbie using romstools, could you guide me, please?
Best regards

Julio,
I don't think that romstools can do this. Send me a mail and I'll help you out.
