constantFastFlux
Description
The constant fastFlux class in OFFBEAT allows you to set the fast flux
and fast fluence fields in files located the starting time folder. If the
fastFlux and fastFluence files are present in the starting time folder, the
internal field and boundary conditions are set accordingly. Otherwise, the
fields are set to 0 n/cm2/s and 0 n/cm2 respectively
in each cell, with zeroGradient BCs in all non-empty/-wedge patches. Note that
when selecting this fast flux model, the fast flux field will remain the same as
it was defined in the starting time folder (or set by default).
Note
Even when constant is selected, the fast fluence keeps being updated at
each time step as:
\(fastFluence = fastFluence.oldTime() + fastFlux \cdot \Delta t\)
Warning
For backward-compatibility, constant can be still used as the typename
for the constant fast flux model. However, its use is deprecated.
