Inquiry about Split Nodes and Fracture Integration in MRST

[ROCKY ZHOU]

Dear Developers,

I greatly appreciate the work you and the team have done in developing this powerful toolbox.

Currently, I am working on integrating run2DCase with validation_DFM for a fractured medium study. My existing mechanical grid is no longer directly applicable after introducing fractures, as I now need to implement split nodes (where nodes along fractures are duplicated, each with their own degrees of freedom but sharing the same coordinates).

My challenge is ensuring that these new split nodes properly align with the flow grid and are consistent with the logic of manager.addFracturedDomain. Before proceeding further, I wanted to ask if MRST already provides built-in tools to:

1. Generate or manage split nodes along fractures for mechanical grids, and
2. Ensure compatibility between these split nodes and the flow grid in the context of addFracturedDomain.

If such functionality exists, could you point me to the relevant functions or examples? If not, do you have any recommendations for implementing this workflow efficiently?

Thank you very much for your time and guidance. Please let me know if you need further clarification.

Best regards
