Dear developers,
I am currently working with MMG in the context of PETSc and have identified
a need to modify the existing MMG interface, DMAdaptMetric_Mmg_Plex(), for
our use case. Given these requirements, I would like to explore the
feasibility of contributing to PETSc to enhance this interface, which has
been verified and validated in our research code.
*Proposed Modifications:*
1.
*Additional Labels for Physical Entities:*
- In addition to the existing bdLabel and rgLabel, our case requires two
additional labels to represent physical vertices and edges within the
computational domain (3D).
- One approach is to introduce two new parameters in the subroutine’s
input list. However, this may require modifications across related
components, such as Pragmatic.
2.
*Support for Open Boundaries:*
- The current interface does not support open boundaries, a feature
available in MMG.
- As a result, several MMG benchmark cases involving open boundary
remeshing cannot be executed within PETSc.
Would this be a viable contribution to PETSc? If so, I would appreciate any
guidance on the best approach to implementing these changes while
maintaining compatibility with existing features.
Looking forward to your thoughts.
Best regards,
Thanks,
Xiaodong
