How do I initialize a MixedFunction

Question

Hello,
I define the space W as:

V_q = VectorFunctionSpace(mesh,'CG',1)
V_T = FunctionSpace(mesh,'CG',1)
W = V_q*V_T

and a function qT as:

qT = Function(W)

How can I initialize the function qT ?

Thanks.

Can you be more specific on how you would like to initialize it?

With constant values.
Thanks

Answer 1

You can do an interpolation of a Constant:

qT.interpolate(Constant((1,2,3)))

The above assumes you are in 2D.
