Scalar within vector innner product Shape mismatch how to calculate

Question

Hi
I have VectorFucntionSpace in RT, FunctionSpace in CG likes this

X = VectorFunctionSpace(mesh, "RT", 2)
Y = FunctionSpace(mesh, "CG", 1)
W = MixedFunctionSpace([X,Y,Y,Y,X,Y,Y])

then i use TrailFunction, TestFucntion likes this

(p,y,p0,p1,p2,p3,z) = TriaFunction(W)
pt,yt,p0t,p1t,p2t,p3t,zt) = TestFunction(W)

After that i have inner product some thing like

a =  inner(div(p),p1t)*dx + inner(y, div(p2))*dx

Error occur: shape mismatch it

Can anybody clarify this to me?

Try to phrase your query as a question. It's not clear what you're asking.

Answer 1

do

y*div(p2)*dx
