Re: [deal.II] Gmsh support on Deal.II Virtualbox image

Dear all, thanx for the immediate support. Turns out Professor Heister was right. I am using an IDE CLion, and I still dont understand everything in it. I moved my .msh file to the cmake-build-debug folder (created when I run my project using that IDE) and was able to read it. Regards Umair On

Re: [deal.II] Re: Some changes in arpack.h (Functionality to compute only eigenvalues)

Animesh, You need to download the patch to the deal.II directory. If you cloned deal.II, you can simply use git apply 0001-Enable-ARPACK-in-regular-mode.patch. If you didn't use git to get deal.II, I think patch -i 0001-Enable-ARPACK-in-regular-mode.patch should work. I have also noted that Arpack

[deal.II] Making ParticlesHandler work with dealii::Triangulation and mesh refinement/coarsening

Hi deal.II Community, I am new to the library and I'm trying to implement a prototype Stokes flow solver with tracer particles using shared memory computing. The overall procedure is something like: 1) Solve velocities and pressure analogous to Step-22. 2) Execute coarsening and refinement 3) I

I am working on deal.II via the VM image (release 9.1.1). I am having trouble reading the .msh file. I even tried running running step 49 and received this error: I believe that's because we forgot to include two files in the release. Does this here help? https://groups.google.com/g/dealii

Re: [deal.II] Re: Gmsh support on Deal.II Virtualbox image

This has nothing to do with DEAL_II_WITH_GMSH. That feature is only required if you use functionality from the Gmsh namespace (https://www.dealii.org/developer/doxygen/deal.II/namespaceGmsh.html). The error message The violated condition was: in Additional information: An input/output erro

Hi, You probably also need to supply the flag *-DDEAL_II_WITH_GMSH=ON* in the cmake line. Best, Aaditya On Tuesday, December 15, 2020 at 1:21:00 PM UTC-5 husain.u...@gmail.com wrote: > > Hello Deal.II community, > I am working on deal.II via the VM image (release 9.1.1). I am having > troub

[deal.II] Triangulation Merge Error

Dear deal.II community As a beginner trying to understand this library I tried to merge two traingulations namely "cheese" and "hyper_cube" by modifying step-1 as - void first_grid () { Triangulation<2> tria1,tria2,tria_merge; /*const double R = 13.0; const double r =7.0;*/ const double

Hi Bruno, I would like to use this patch to compute the smallest eigenvalues in my case. Could you please let me know how should I update my source code in the arpack.h header file to accommodate
