Function documentation

static tk::InitializeFn::result_type inciter::CompFlowProblemSodShocktube::initialize(ncomp_t, const std::vector<EOS>&, tk::real x, tk::real, tk::real, tk::real)

Initialize numerical solution.

Parameters
in X coordinate where to evaluate the solution
Returns Values of all components evaluated at (x)

Evaluate analytical solution at (x,y,z,t) for all components

This function only initializes the Sod shock tube problem, but does not actually give the analytical solution at time greater than 0. The analytical solution would require an exact Riemann solver, which has not been implemented yet.

static tk::InitializeFn::result_type inciter::CompFlowProblemSodShocktube::analyticSolution(ncomp_t, const std::vector<EOS>&, tk::real x, tk::real, tk::real, tk::real)

Evaluate analytical solution at (x,y,z,t) for all components.

Parameters
in X coordinate where to evaluate the solution
Returns Values of all components evaluated at (x)

Evaluate analytical solution at (x,y,z,t) for all components

static tk::SrcFn::result_type inciter::CompFlowProblemSodShocktube::src(ncomp_t, const std::vector<EOS>&, tk::real, tk::real, tk::real, tk::real, std::vector<tk::real>& sv)

Parameters
sv in/out Source term vector

Compute and return source term for this problem

std::vector<std::string> inciter::CompFlowProblemSodShocktube::analyticFieldNames(ncomp_t) const

Returns Vector of strings labelling analytic fields output in file

std::vector<std::string> inciter::CompFlowProblemSodShocktube::names(ncomp_t) const
