v55 v56 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. A schematic of the loop is as follows: :[[Image(LoopSR.png, 35%)]] 119 iii.
