Dear Martin,
I get the meaning, you are right.
And in this case
if
VectorizedArrayType local_diagonal_vector[phi.static_dofs_per_cell];
change to
VectorizedArrayType local_diagonal_vector[phi.static_dofs_per_component];
should also work, right?

I should add that you can set a variable coefficient, but it is still
scalar and thus the same to all components, so the code is correct. It
would be different if we allowed tensor-valued coefficients (which we do
not at the moment); then, one would really need to go through all

Dear all,
The function MatrixFreeOperators::LaplaceOperator::local_diagonal_cell() in
matrixfree/operators.h line 2135-2153
FEEvaluation phi(
data, this->selected_rows[0]);
for (unsigned int cell = cell_range.first; cell < cell_range.second;
++cell)
{
phi.reinit(cell);
