Hello all, I have a question that I wish someone could help. Truly appreciate! I have a 2-sphere mesh that is spited into two regions, which an internal boundary as their interface. I would like to access/set the all values of a function that is below/above the internal boundary (in this case, a h…

The point is that the “+” and “-” restrictions are only to be used with dS integrals, where they usually are random. In your code you are doing several things that does not make sense: use the restrictions “+” and “-” in project. Project is a function that integrates over dx, where restrictions do…

Hello @dokken , Yes, I am aware of the post. However, I am confused on getting the values below/above the interface in each subdomain respectively, not integrating along the boundary.

Hello @dokken , That seems working, and thank you for the example!
