Does TUFLOW FV lose or gain mass?

Recommended Posts

How does TUFLOW FV handle mass balance? Is it like the old finite element models, with mass varying in different parts of the mesh domain?

TUFLOW FV applies the finite volume numerical method for its computational scheme. A feature of the finite volume method is that it conserves mass to numerical precision for all cells and for the entire computational domain. This is valid down to single precision accuracy for the TUFLOW FV engine build used in the study.

 

Mass balance can be checked via flux outputs along nodestrings and also by specification of the “volume” output parameter specification (See the User Manual).
