constantBurnup

Description

The constant burnup class in OFFBEAT allows you to set the burnup field in a file located in the starting time folder. If the Bu file is present in the starting time folder, the internal field and boundary conditions are set accordingly. If the Bufile is not present, the burnup field is set by degault to 0 MWd/MT\(_{oxide}\) in each cell, with zeroGradient BCs in all non-empty/-wedge patches. oNte that.

When selecting this burnup model, the burnup field will not evolve over time and will remain as defined in the starting time folder (or as set by default by OFFBEAT).

Note

At the moment, the constant model is the correct burnup model to use if you are coupling OFFBEAT to an external solver that provides the Bu field directly. At every coupled iteration, simply substitute the Bu file generated with the external solver in the starting time folder and (re)start the OFFBEAT simulation.

Warning

For backward-compatibility, fromLatestTime can be still used as the typename for the constant burnup model. However, its use is deprecated.
