Figure 9.6: Mass of water in domain over time

Overview of mass output UDF The time and the mass of water in the domain at the
different time steps have been stored as vector attributes. For this purpose, the following lines
were added in the private attribute section of the mass output class declaration:
std::vector<double> Time;
std::vector<double> Mass;

Two functions are declared in the public section of the mass output class declaration

• update time mass: appends time and mass to Time and Mass vectors when called

• write time mass: writes Time and Mass vectors to a file

Description of mass output.cxx The two functions mentioned above are defined in mass output.cxx.

update time mass function The update time mass function can be split into 3 distinct
parts

• Part 1: variable declarations

• Part 2: access and processing of TransAT data

• Part 3: data communication
