Here is an observation.
I set
DYLD_FALLBACK_LIBRARY_PATH=/path/to/spack/view/lib
and run as
./step-40
then it runs fine.
But if I use “make run”, then it cannot find libumfpack !!!

Hi everyone.
I'm looking for a solver to solve a fluid-structure problem, like a heart
valve: the valve is an elastic material, and the blood could be considered
as an incompressible fluid (evolutionary incompressible Navier--Stokes
equations).
In step-46 I see a Fluid-Structure interaction
Hi Ramiro,
step-46 can be indeed extended to "realistic" FSI (a student of mine did
it some time ago; but requires a bit of work of course).
As alternative, my deal.II-like tutorial step can also serve the purpose

with the code documented as a true
Please have a look at this particular test which showcases how an outer
product can be achieved with deal.II!

Hope this helps!

Hello everyone,
I am trying to recast a current FullMatrix as a
SparseMatrix in order to add this matrix to another
SparseMatrix.
I have tried something like this:
SparseMatrix Mat_Sparse;
Mat_Sparse.copy_from(Mat_Full);
Mat_Sparse_2.add(1.,Mat_Sparse);
When doing so I receive the

Hi, there!
Still on the course of learning dealii by reading through the tutorials.
Came up with the following observation.
1. In Step-4, a single QGauss object was created in assemble_system(),
and was used later in assemble_system().
2. In Step-23, multiple copies of the same QGauss
