[deal.II] Re: Steps 14 in 3D

Dear Elena, You have asked a question that is beyond the scope of expectation for this forum . Right now you're essentially asking someone to do your preliminary work for you, which is unfair. Part of the way to learn deal.II and becom

Re: [deal.II] transitioning from parallel::shared::Triangulation to parallel::distributed::Triangulation

Alberto, I am bothering today about a code I have been writing in the shared triangulation framework and its transition to the parallel::distributed::Triangulation framework. The shared version works just fine, and so does the parallel if run with 1 single process. I understand therefore th

This code triggers a safety mechanism that I introduced recently (April 26). We also see this on one of the test machines: https://cdash.kyomu.43-1.org/viewBuildError.php?buildid=8758 but I previously thought this is only due to a leftover in the configuration and I did not see it in real life b

[deal.II] Re: define 2D/3D Point

Lisa, you can write something like Point p; switch(dim) { case 1: p = Point (1); break; case 2: p = Point (1, 2); break; case 3: p = Point (1, 2, 3); break; default: Assert(false, ExcNotImplemented()); } const Point test_point = p; Best, Daniel -- The dea

[deal.II] Steps 14 in 3D

Dear Friends, I want to change step 14 to run a 3D model. I know that in deal ii many parts are dim independent and by changing dim to 3, automatically many parts work for 3D and do not need any modification. I want to know, for 3D model which parts should I change in step 14. In general I know

[deal.II] define 2D/3D Point

Hello, I would like to define a constant 2D/3D point, but I can not do it. Maybe my question is more a C++ question than a Deal ii, but I would appreciate it if someone help me. I want to write something like: switch (dim) { case 2: const Point test_point (value1, value2);

This is very strange. Do you set the AVX flags yourself? @Martin have you ever seen something like that? Bruno 2017-07-07 3:50 GMT-04:00 Victor Eijkhout : > Hm. That second compile line should be: > > > > > > > > > > [ 63%] Building CXX object > source/numerics/CMakeFiles/obj_numerics_debug.dir/

I have the following three PDEs (reduced from a more complex version): Now I am stuck. Usually I convert them to a discretized form (as for exam

Hm. That second compile line should be: [ 63%] Building CXX object source/numerics/CMakeFiles/obj_numerics_debug.dir /vector_tools_boundary.cc.o cd /tmp/dealii-build/source/numerics && /opt/intel/ compilers_and_libraries_2017.4.196/linux/mpi/intel64/bin/mpicxx -DDEBUG - DTBB_DO_ASSERT=1

[deal.II] Re: CMake extra libraries?

Yay! Finally compiling. Mind if I just continue in this ticket even though the question is moving on? I think I'm correctly specifying a bunch of AVX flags to trilinos. In the deal build they show up in compile lines such as: [ 63%] Building CXX object source/physics/CMakeFiles/obj_physics_rel
