bool AMP::Operator::DiffusionTransportModel::d_UseBilogScaling

protectedinherited

Use a bilogarithmic scaling of material arguments.

The chemical diffusion equation is

\[ \partial_t u = \nabla \cdot (K \nabla u). \]

Sometimes the variable \(u\) is physically restricted to be within a certain range, such as \( u \in [0,.2] \) for hyper non-stoichiometry. These bounds can wreak havoc with the convergence of nonlinear solvers. We can employ the transformation \( U=\log( (u-a)/(b-u) ) \) or \( u = (a+ b \exp(U)/(1+\exp(U)) \) to change to a variable \(U\) that ranges from \((-\infty, \infty)\). For any value of \( U \) it is rigorously true that \( a<u<b \), alleviating the problem of solver iterations sending the solution into forbidden territory. The equation for \(U\) is

\[ f(U) \partial_t U = \nabla \cdot (f(U) K \nabla U), \]

where \( f(U) = (b-a) \exp(U) / (1+\exp(U))^2 \). This adds a well-behaved mass matrix to the chemical diffusion equation and modifies the diffusion coefficient by the same factor. When using this transformation be sure to transform initial and boundary conditions as well in the input files. You have to specify this transformation in the mass operator for the chemical equation. The transformation must be specified within all operators using materials that depend on the transformed variable. When such an operator acts on a variable other than BilogVariable, you must specify "BilogScaleCoefficient=FALSE". Be sure to also to transform the default variables specified for this DiffusionTransportModel.

The thermal diffusion equation is

\[ \rho C_P \partial_t T = \nabla \cdot (D \nabla T) \]

The bilogarthmic transform may also be used with this equation to give

\[ \rho C_P f(T) \partial_t T = \nabla \cdot (f(T) D \nabla T), \]

with similar considerations as for the chemical equation.
