PorousFlowExponentialDecay
!syntax description /Kernels/PorousFlowExponentialDecay
Description
The residual computed by PorousFlowExponentialDecay
is where is the variable, and and are AuxVariables
(or real values). Combined with a TimeDerivative
Kernel
, this is useful for simulating exponential decay of . One example is simulating heat loss using the Lauwerier model.
