hi all

i'm trying to write C code for supersonic flow over flat plate. i'm reffereing CFD by JD anderson chp 10. i have a few doubts hope u can help.

firstly when i'm calculating vector E at plate surface and vector F at inflow, what should be the values of txy, txx, tyy, qx and qy, should i consider. should i take all of them to be zero...???

and after prdictor step, when calculating txy, then in one of the terms we need to calculate central difference, so our expression is something like....
U(i+1,j)-U(i-1,j) but we dont have values for U(i+1,j) at time step t+dt, right...??? so am i suppose to use the values calculated at previous time step.... coz that is the only way... jz needed to confirm..

thanks once again
