Function documentation

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

Initialize numerical solution.

Parameters
ncomp in Number of scalar components in this PDE system
mat_blk
x 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.
