hi junta!! i have a serious problem in the algorithm for solving the pressure-poissons equation ..i am writing my own code FTCS explicit with primitive variables and i am unable to write a general code for a body underwater as the body has its own irregular boundary...and thus am having a lot of probs with the boundary conditons and the staggered grid.... . i am using a cartesian grid.. have not transformed the grid.. so does anybody have an idea on this??? DO I HAVE TO TRANSFORM THE GRID?? thanks for all.. and long live this forum. luv yogi

Here's your solution: Buy a copy of my soon-to-be-released 2-part paperback book, "INCOMPRESSIBLE FLOW AND THE FINITE ELEMENT METHOD", John Wiley and sons. A BIG, expensive, hardcopy is actually available now....
