I am trying to generate a curvilinear grid: I am working on Fjords and I want to make a nested model inside a big regional model that I have already created. I want to do this submodel on a specific fjord, a part of this fjord (so my area is like an open chanel with some little islands every where).
I have selected the coeast lines that I need for this specific region. When I go to Mohid GIS -> Data items -> new data item -> curvilinear grid, then I put the name of the output file which will contain this grid, and then I select my coast lines of the chanel. A message error appear:
Code: Select all
Less than 3 corners in the image region
Error generating the grid, please check log file for details
I don't really understand the message, and also: could you tell me what is NPPE? (and could you confirm me that NX and NY are the number of horizontal and vertical cells?)
Thank you in advance for your help
Have a nice day!!
