Bicgstab method
 

can anyone suggest good referances or codes for implementation of Bi - conjugate gradient method for solution of pressure poisson equation??

thnx in advance . . .

netlib.org has plenty of code. It is not necessarily the most efficient on current processors, but it will be fully illustrative of the algorithm and give reference results with which to compare.
