===Q. Does the HPC 2D solver produce the same results as the Classic 2D solver?===
No, TUFLOW Classic uses a 2nd order ADI (Alternating Direction Implicit) finite difference solution of the 2D SWE, while the HPC solver uses a 2nd order explicit finite volume TVD (Total Variation Diminishing) solution (a 1st order HPC solution is also available). As there is no exact solution of the equations (hence all the different solvers!), the two schemes produce different results. <br>
