Re: unstructured mesh

Hi Sanjin,

Ferret does not have a native ability to deal with an
unstructured mesh. However, Ferret has two capabilities that can
allow you to adapt it to the task:

  1. It can contour on arbitrary curvilinear coordinate systems
     so long as the underlying topology of the data looks like a
     simple matrix
  2. You can write your own FORTRAN or C code into a Ferret
     "external function" it will be linked  dynamically

If you can conceive of a 2D coordinate system that would
represent your data well graphically (curvilinear_x,
curvilinear_y) and you can write a regridding function


then you can solve your problem.
