Description

The residual computed by PorousFlowExponentialDecay is $var element = document.getElementById("moose-equation-f7cbf148-6eb9-461a-8136-7ccecfe1ebb0");katex.render("\\mathrm{residual} = r(u - u_{\\mathrm{ref}})", element, {displayMode:true,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ where $var element = document.getElementById("moose-equation-1cf96282-099b-40ff-bae9-e83dfa037b06");katex.render("u", element, {displayMode:false,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ is the variable, and $var element = document.getElementById("moose-equation-a6e223b4-f32d-4126-b37d-d662b9d3e1a8");katex.render("r", element, {displayMode:false,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ and $var element = document.getElementById("moose-equation-ab737d06-b1d1-46d5-beea-0fa6f4dc928d");katex.render("u_{\\mathrm{ref}}", element, {displayMode:false,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ are AuxVariables (or real values). Combined with a TimeDerivative Kernel, this is useful for simulating exponential decay of $var element = document.getElementById("moose-equation-5a724a8e-6951-433d-a3b6-eef33a5ba05e");katex.render("u", element, {displayMode:false,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ . One example is simulating heat loss using the Lauwerier model.
