Re: [deal.II] Re: Deal.II does not pass quick tests after installation

Thank you very much Mr. Pelteret for handling the case! Mr. Wells, I have tried compiling the library without using pthreads. The quicktests are now passed successfully [image: Hình ảnh nội tuyến 1] For the other question, we have CentOS 5.3 installed in our machine. But I have installed necess

[deal.II] geometry

Dear All, I want to create a quarter of a circle in deal ii. In this case, I could create half of a circle with half_hyper_ball. I have tried GridTools::delete_unused_vertices or GridTools::transformation to remove or shift the same vertices to eliminate half of the circle. It would be very ki

Dear all, I am trying to compile the dealii-8.4.1 with trilinos-12.4.2, p4est and MPI. As I begin to compile the dealii I become the error following and I dont know how should I fix it. I become the MPI version 2.0 as I give the command 'mpiexec --version' but during dealii compile I see MIP_V

[deal.II] External point forces on elastic bodies

Dear Friends, I want to solve a very simple elastic problem to obtain stress and displacement field, applying a point force on one of the external surfaces of a rectangular 2D domain. Although I found some sort of external forces only in step 8, it is not a point force. I was wondering how to a

Hi Reza, Something is certainly wrong with your build. Please open a new topic for this issue. Alternatively you can try building deal.II using tools like: Spack https://github.com/dealii/dealii/wiki/deal.II-in-Spack Candi https://github.com/dealii/candi Kind regards, Denis > On 12 Jul 2016, a

Dear Rajat, Well, since the solver gets to 900 iterations (time steps?), its most likely a numerical or implementational issue rather than a installation issue. I was under the impression that your linear system couldn't be solved at all.Is there any adaptive refinement being performed or somet
