Dear David， I am under the directory: ../dealii-9.0.1/dealii-9.0.1 and use the command line in "cmake" $cmake ../dealii-9.0.1/dealii-9.0.1 (which is the file that was unziped) -DCMAKE_INSTALL_PREFIX=../dealii-9.0.1/build (which is the new and empty) and this has errors; Best, Chucui 在 201

Hi Chucui, StraightBoundary was removed in deal.II 9.0; it should not show up in any object files so these errors don't make any sense. Did you use a clean build directory? Thanks, David Wells On Thursday, October 18, 2018 at 8:27:40 AM UTC-4, chucu...@gmail.com wrote: > > Dear all, > > I wan

[deal.II] Re: Computing min and max eigenvalues

Michal, Have you tried to use ARPACK to get the smallest eigenvalues? That's what we are doing in one of our code and it works pretty well. We have a patch here so that you don't need to provide t

[deal.II] Re: Several questions about mesh generation and distributed triangulations

I am by the way aware of the parrallel::distributed::Triangulation constructor which accepts another Triangulation as an argument - however this calls repartitioning and is therefore no solution to the problem. Also weights could be passed to influence the partitioning, but determining weights s

[deal.II] Computing min and max eigenvalues

Dear all, I need to compute the minimum and maximum eigenvalues of the matrix-free operator (vmult is only available ). For the largest eigenvalue, I'm using the power method, but I have some problems with minimal eigenvalue. The condition number of the operator is close to 1, so I tried using t

[deal.II] After "make install", there are some Errors when install Deal.II-9.0.1

Dear all, I want to reinstall my deal.ii because I need to run some codes in parallel just like Step-40, step-55 and Step-32, and I choose deal.ii-9.0.1 The command lines I use are: $cmake ../dealii-9.0.1/dealii-9.0.1 -DDEAL_II_WITH_MPI=ON -DCMAKE_C_COMPILER=/usr/local/mpi3/bin/mpicc -DC

[deal.II] Several questions about mesh generation and distributed triangulations

I will try to be as short as possible - if more details are required feel free to ask. Also I offer to submit all mesh generation code I create in the future, since others might have similar needs at some point. I work on a 3d mesh with purely axis-parallel edges. The mesh is a 2d-mesh (say in
