 Sorry but I want to add a question here. What's the recommanded  way to 
 import a mesh from cubit to deal.ii?
 I tried read_abaqus and read_ucd with following error:
 [image: Snipaste_2022-12-07_18-14-08.png]
 I‘m using Cubit 2022.4. In deal.II documentation it supports Cubit 11.x 
 to 15.x, does it mean Trelis 15.x? [Cubit download 
 ]
 At least in Trelis 16.5 there's no "Export using Cubit ID's" to uncheck.

Re: [deal.II] Hoe to merge hyper_cube_with_cylindrical_hole with hyper_ball()

2022-12-07 Thread Daniel Arndt 
Deepika,

You will need to appropriate manifolds ids and manifolds after merging the
triangulations. Also, you need to make sure that the coarse triangulations
share the same vertices and edges at the interior boundary.

Best,
Daniel
