Boundary normal is in a MultiCutFab
with AMREX_SPACEDIM
+components representing the unit vector pointing toward the covered part.
Boundary area is in a MultiCutFab
with a single component
+representing the dimensionless boundary area. When the cell is isotropic
+(i.e., \(\Delta x = \Delta y = \Delta z\)), it’s trivial to convert it
+to physical units. If the cell size is anisotropic, the conversion
+requires multiplying by a factor of \(\sqrt{(n_x \Delta y \Delta
+z)^2 + (n_y \Delta x \Delta z)^2 + (n_z \Delta x \Delta y)^2}\), where
+\(n\) is the boundary normal vector.
Face centroid is in a MultiCutFab
with AMREX_SPACEDIM
components.
Each component of the data is in the range of \([-0.5,0.5]\), based on
each cell’s local coordinates with respect to the embedded boundary.
