Is mixedfunctionSpace with lagrange element and vectorfunctionSpace with lagrange element are same

1

Dear Sir,

Thank you for your reply to my previous questions.

I have one more doubt regarding function space.
is it possible to produce the same answer if I use V=vectorfunctionspace(mesh, “CG”, 1) instead
Q=Finiteelement(“CG”, mesh, 1)
V=functionspace(mesh, mixedelement([Q, Q] )) …

advance thanks for answer

VectorFunctionSpace assumes your variables will be vector, like speed. FunctionSpace creates a scalar, like pressure, density, viscosity.
