Thanks Lawrence, I should note that w1.rename("foo") w2.rename("bar") only works after a w1, w2 = w.split() command, but not after the split(w). I would indeed be helpful to apply names to the components using the "name" option of the function in the mixed space. Colin, I just didn't like the names function_8 etc that Paraview shows if you output multiple fields. Best, Anna.

Dear all,

How can I name the components of a function in a mixed function space, so that I can then easily visualize the results based on their names?

For example, say that I have

V = FunctionSpace(mesh, "CG", 1) W = V*V

w = Function(W) w1, w2 = split(w) w1.rename("foo") w2.rename("bar")

If you don't do this, we give you names like:

w_name[cmpt-0], c_name[cmpt-1] which is not very helpful.

When you first make a function you can do:

w = Function(W, name="some_name")

we could extend the API to allow you to pass a list of names that apply to the components. This would be easy to do if you'd like to try.

...

output_file = File('results.pvd') output_file.write(w1, w2, time=t)

I would like to give names to w1 and w2. Lawrence
