B-char approximates traceback cells by balls and uses an adjustment plus least-squares step to build a mass-conserving ELLAM-type scheme that runs much faster than polytopal implementations, with similar accuracy in 2D and 3D tests.

An efficient implementation of mass conserving characteristic-based schemes in 2D and 3D
B-char approximates traceback cells by balls and uses an adjustment plus least-squares step to build a mass-conserving ELLAM-type scheme that runs much faster than polytopal implementations, with similar accuracy in 2D and 3D tests.
