◆ enforceDivergenceFreeConditionAtBoundary() [1/2]

Set normal velocity ghost cell values to enforce discrete divergence-free condition in the ghost cells abutting the physical boundary.
- Note
- The default behavior is to set these values only in cells adjacent to boundary locations where normal traction conditions are imposed. Values can also be set where normal velocity boundary conditions, or both.
