what happens after loading dealii with `spack load dealii`, if you try to
build (from scratch) `step-40`?
Can you send us the output of cmake and make?

Are you running the terminal, or the deal.II application?
When you run the deal.II application, you are dropped into a terminal (with
instructions) to run deal.II examples. Including how to set up your bashrc (or
zshrc) to point to the deal.II
Installation/the module command.
Only after you
The 9.0.0 image contains a spack installation. Can you run "module load
dealii" before trying to run?

Did you actually read the error message? :-)
It tells you exactly what you have to do. In particolar, you are using
bc.gradient to evaluate the Neumann boundary value, but you did not implement
the gradient in your Neumann.h file. This explained in detail in the error
message you got.

Take a look at your parameter file. It is probably trying to write output file
to a directory that does not exist.

If you are using version 9.3pre of deal.II, kdtree was removed. Use RTree
instead, which is faster and more flexible.

The interpolated field says that the field value is zero (on the line above
your arrow). This is how it is documented: if a particle is removed, its
interpolated value is left unchanged in the target vector. Zero in your case.

It is unclear what it means to transfer a solution for FE_FaceQ. On refined
cells, the central part of the skeleton cannot be transferred from the outer
skeleton (I.e., a refined grid is not a subspace Of the coarse grid), so
technically we cannot transfer solutions for FE spaces

Are you using an example from deal.II master? If this is the case, the example
looks for 9.3pre but the image we provide only has 9.1 installed. Try
inspecting the CMakeList.txt to see which version is being looked for, and try
changing to 9.1.

Currently, this is also the simplest way:
Take a look at the documentation of the add parameter method.
Are also available to simplify what you want to achieve.
The examples you are using are likely looking for deal.II 9.2.pre. Try changing
the makefile, and see if that works. :-)

More information on the course schedule is available here:
A limited number of seats is available for external PhD students, postdocs, and
researcher. No fee is required, but registration is mandatory.
To reserve a seat, please complete
Take a look at the Particles namespace, and at the rtree boost documentation
(we wrap rtree from boost into the RTree alias, which is compatible with
Point, BoundingBox and Segment).
The tests/boost directory contains some examples that may be useful.

You are trying to read a vtk file that was generated by DataOut.
Try to write the file with GridOut::write_vtk.
DataOut produces files that are split cell wise (to allow for some flexibility
in discontinuos fields.

I just uploaded a version of deal.II 9.1.0pre (master version of yesterday)
This was compiled with clang 6.0.0, downloaded from the officia

I just finished uploading a new brew based package for deal.II with a 9.0pre.1
It was compiled on a Mac OS X High Sierra: 10.13 (17A405), with Xcode 9.0.1
The application contains a full `spack

In the options of xcode, you should be able to install also the 10.12 sdk. Can
you try that?
