v52 v53 117 117 i. Call Bcond  Boundary condition SR that sets left and right ghost zones to adjacent physical cells (recall boundary conditions are set to transmissive). 118 118 ii. Call CFLcond  Computes timestep using cfl coeff and max speed, where the max speed is also computed in this SR. 119 iii. Call GetFluxes  This SR sets up the local Riemann Problem (LRP) and solves it exactly to get rho(x/t), u(x/t), P(x/t) at x/t = 0 (see above explanation of sampling routine). This is the most complicated structure of the program. 119 iii. Call GetFluxes  This SR sets up the local Riemann Problem (LRP) and solves it exactly to get rho(x/t), u(x/t), P(x/t) at x/t = 0 (see above explanation of sampling routine). This is the most complicated structure of the program. A schematic of the loop is as follows: 120 120 121 121 [[Image(LoopSR.png, 35%)]] 122 122 123 i v.
