static InputParameters validParams()
unsigned int _qp
The current quadrature point.
Base class for postprocessors executed on one or more sidesets.
const VariableGradient & _grad_u
Holds the solution gradient at the current quadrature points.
SideVariablePostprocessor(const InputParameters ¶meters)
virtual void execute() override
Execute method.
const VariableValue & _u
Holds the solution at current quadrature points.
virtual void computeQpValue()=0
This is what derived classes should override to do something on every quadrature point on every eleme...
