The fluid density is implicitly initialized with a uniform field because the fluid is incompressible and homogeneous. No data set is therefore required.
The initial fluid temperature is uniform over the domain.

The initial velocity field is defined by spreading out the inflow velocity profile. This choice allows us to ensure a perfect flowrate conservation between inflow and outflow for the first time step.
