Making scalar values with Frobenius inner product of two 2nd order tensors
Asked by
Sungick Kim
Hi.
I want to calculate a scalar value(strain energy) with two 2nd-order tensors.
In the FFC User manual,
dot(A, B) = A:B =sum(A_ij*B_ij) #When A and B are 2nd order tensor.
But it seems not working. When I tried to project the result error poped up.
Error message is
'ufl.log.
My code is written below.
Q = FunctionSpace(mesh, "CG", 1)
P=dot(A, B)
ans = project(P, Q)
