All, Please provide me with a sanity check of where the initial conditions get set in the Laplacian program example 45 Currently I assign the initial voltages to a 3-D array called barray in ComputeRHS, these very between 0 and 100; I initially believed initialization was occurring in ComputeRHS, but because my final output goes from 0 to 1, I am questioning my understanding of where the initial conditions go. Can you set me straight? Thanks John
