Re: [deal.II] Visit sees *.vtu-files as 3d-files instead of 2d-files for n > 16 threads

I did several more experiments, using both my program and example programs from deal.II (such as step-40 and step-55). When using my program, I still got the same result as before, if I have more than 16 threads, then my result gets interpreted as 3d, not as 2d. When using step-55, I can use 24

Re: [deal.II] Can GridIn read 3D quad mesh?

Dear Shawn, No, its fine. I see that the changes weren’t as drastic as I thought they’d be, so I think that the boundary ID assignment will work out of the box (I’d forgotten that someone else had already done much of the work necessary to support codim-1). I’ve made a patch to add this funct
