Re: [deal.II] [Assigning boundary condition to node]

[Daniel Arndt]

Can specify what you mean by "assign a certain BC [boundary condition] to a
node"? Typically boundary conditions only make sense on the boundary of a
mesh with codimension 1 (embedded in the same physical space).
Thus, you would only consider setting boundary conditions on a node/point
(0-dimensional) if you are dealing with a 1d-mesh.
You can, of course, just add a constraint for a specific degree of freedom
in your AffineConstraints object, also see step-11.

Best,
Daniel

[deal.II] Re: Modifying Cmake to have Deal.ii include paths

[Bruno Turcksin]

Hello,

You can just set DEAL_II_DIR in your environment. If you are using bash you 
can do `export DEAL_II_DIR=/path/to/deal.II` in your terminal or put that 
line you .bashrc if you want to do this permanently. Personally, I just 
write the cmake line in a file and make the file executable. When I need to 
call cmake, I just call the executable.

Best,

Bruno

Re: [deal.II] Modifying Cmake to have Deal.ii include paths

[Nils Schween]

Hi Xavier,

i think the following command will do:

set(DEAL_II_MIN_VERSION "9.5.0")
set(DEAL_II_DIR "~/.local/lib/dealii")
find_package(deal.II ${DEAL_II_MIN_VERSION} REQUIRED
 HINTS ${DEAL_II_DIR} ../ ../../ $ENV{DEAL_II_DIR})
IF(NOT ${deal.II_FOUND})
MESSAGE(FATAL_ERROR
  "*** Could not locate a (sufficiently recent) version of deal.II. ***\n"
  "You may want to either pass a flag -DDEAL_II_DIR=/path/to/deal.II to cmake"
  " or set an environment variable \"DEAL_II_DIR\".")
ENDIF()

Regards,
Nils

[deal.II] Modifying Cmake to have Deal.ii include paths

[Xavier Johnson]

Hi,

This may be a newb question. I am probably struggling understanding how to 
set paths in cmake and spent some time reading the documentation for cmake.

My question is, how can I set the DEAL_II_DIR in the CMakeLists.txt so I 
don't have to provide a path every time I call the cmake command?

Thanks
