Dear Animesh,
Let me preface my suggestion by saying that you can introduce some
heterogeneity in more than one way. That is, you're not bound to using a
material ID (which is what I'm going to suggest), but you could use some
geometric arguments to determine which class or material properties
Matthias,
When you helped me implement the operator N_c which is added to my
linear_operator , i.e.
auto N_c = temp1_coef*M + temp_coef*Kronecker;
auto system_matrix = linear_operator(linear_part) + N_c;
the first term is not complete.
Really I want,
auto N_c = temp1_coef*|Psi^m|^2 *M + t
Dear Nikki,
A "linear operator" in deal.II is an object that linearly transforms a
vector into another one, i.e., it has a vector space as domain of
definition and a vector space as range space.
In your case M.matrix_scalar_product(u,u) is (u^T M u), this is a
quadratic operation, not a linear
Hello all,
I am struggling to turn a matrix scalar product into a linear operator. I
currently have:
temp = M.matrix_scalar_product(u,u);
and I need to turn 'temp' into a linear operator.
I have tried turning 'M' into a linear operator first and then performing
the multiplication and have

Hi Timo,
Thanks for you suggestion. I tested step-1 and step-2 again and they ran
successfully after I set the number of OpenMP threads to 1. I only plan
plan on running MPI codes without any multi-threading. The BLAS
implementation I am using is a part of the Intel MKL library which is

Can you try setting
export OMP_NUM_THREADS=1
before running any of the examples?
If you are planning on running MPI-only codes, you don't need to use
OpenMP in your BLAS implementation.

Hello All,
I am trying to solve the wrinkling problem of a thin stiff film attached to
a soft substrate in dealii. I am using the code - from the code gallery for
this purpose. For the simulations, I would have to consider the film and
the substrate with different material properties.
