[Maxima] Vorticity Calculations

[Lorenzo Isella]

Dear All,
I am starting to delve into fluid mechanics. Though I will use
extensively Fortran or C for computational tasks, I am interested in
analytical results.
I am sure that Maxima is capable of working ouyt cross products, but I
wonder if it is any difficult to work out the curl of a vector field,
as it is needed for instance when I want to get the vorticity (defined
as the curl of a velocity field).
Many thanks

Lorenzo
