class EJ_Diffusion

A general class for solving diffusion problems using the explicit jump method.

Implemented in diffusion based material property modules which use the explicit jump method.

Public Functions

EJ_Diffusion(puma::Matrix<double> *T, puma::Matrix<double> *kMat, char dir, double solverTol, int solverMaxIt, bool print, puma::Printer *printer, int numThreads)

A constructor which takes in the parameters used for calculating the diffusion coefficient using the explicit jump method.

Parameters

T – a pointer to a puma matrix to store the resulting solution field.
kMat – a point to a puma matrix containing the diffusion coefficient at each point
dir – a char specifying which direction to run the simulation in (should be ‘x’, ‘y’, or ‘z’).
solverTol – a double specifying the convergence criterion for the iterative solver used.
solverMaxIt – an integer specifying the maximum number of iterations the solver may execute before exiting.
print – a boolean which specifies whether the the number of iterations and residual are printed after each iteration of the solver.
numThreads – an integer which specifies the number of threads used for the simulation.

~EJ_Diffusion()

puma::Vec3<double> compute_DiffusionCoefficient()

computes the diffusion coefficient using the parameters specified when constructing the object.

Returns: a puma vector containing the diffusion coefficient in the x, y, and z directions.

Public Static Functions

static bool computeKMatrix(puma::Workspace *segWS, std::map<int, double> matCond, puma::Matrix<double> *kMat, int numThreads)

computes a puma matrix which contains the diffusion coefficient at each cell in the domain.

Implemented in diffusion based material property modules which use the explicit jump method.
