Description !syntax description /UserObjects/InterfaceQpValueUserObject

InterfaceQpValueUserObject is a user object computing and storing average variable values or rates across an interface for each quadrature. The kind of average value are the one available in InterfaceValueTools. The value type stored by this userobject is selected via the value_type input parameter. For example to get both the variable value and variable rate the user must add two separate user objects in the input file.

The InterfaceQpValueUserObject can provide two types of values to other MOOSE systems:

  • a qp value by calling getQpValue

  • an element side average value by calling getSideAverageValue

The stored value can be converted into an AuxVariable by using InterfaceValueUserObjectAux AuxKernel.
