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

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

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

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
