virtual Real computeQpResidual() override
The user can override this function to compute the residual at a node.
static InputParameters validParams()
Constructor initializes the rate.
virtual Real computeQpJacobian() override
The user can override this function to compute the "on-diagonal" Jacobian contribution.
ConstantRate(const InputParameters ¶meters)
DIE A HORRIBLE DEATH HERE typedef LIBMESH_DEFAULT_SCALAR_TYPE Real
const Real & _rate
The rate.
const InputParameters & parameters() const
Get the parameters of the object.
Represents the rate in a simple ODE of du/dt = rate.
Base class for creating nodal kernels with hand-coded Jacobians.
