Hi, for 4×4 system of PDEs, I considered trial and test functions mixed of 4 function spaces as the following: V1 = FunctionSpace(mesh, "CG", deg) V2 = VectorFunctionSpace(mesh, "CG", deg) V3 = TensorFunctionSpace(mesh, "CG", deg) P = FunctionSpace(mesh, "CG", deg) V = V1 * V2 * V3 * P u, g, H, p = TrialFunction(V) phi1, phi2, phi3, q = TestFunction(V) but I got the following error Traceback (most recent call last): File "test1.py", line 58, in <module> u, g, H, p = TrialFunction(V) ValueError: too many values to unpack (expected 4) Many thanks if someone could give me some direction about that. Best, Amireh
Dear Amireh, That’s TestFunctions, TrialFunctions instead of TestFunction, TrialFunction. On Sunday, 24 June 2018, Amireh Mousavi <amireh.mousavi@math.iut.ac.ir> wrote:

but I got the following error

Many thanks if someone could give me some direction about that. Best, Amireh
