Here’s a topic to which I’ve been asked multiple questions following the recent seminar.
Consider a “complex” part:
Typically, a conforming all-hex mesh would be created via block decomposition:
And of course, the block decomposition process is one of the primary contributors to the total meshing time.
However, it would seem that a non-conforming hex mesh (i.e. mesh with T-Junctions) would seem to allow for simpler block decompositions:
Sometimes in traditional FEA the analyst will apply a tie between the non-conforming surfaces, as long as it’s in a region sufficiently far away from the region of interest.
Series of questions I’ve been asked:
- Do volumetric U-Splines allow for “T-Junctions”?
- How would these non-conforming interfaces perform compared to tied interfaces?
- How would these non-conforming interfaces perform compared to conforming interfaces?
- Would the final image be a “good” non-conforming mesh?
