A note on the regularization of the discrete Poisson-Neumann problem. (English) Zbl 1034.76043
The time integration of incompressible flow equations leads to a Poisson problem for pressure with Neumann boundary conditions. This problem has a solution only if a compatibility condition is fulfilled. Here the author considers a regularization of the problem, and applies the method to a lid-driven cavity flow.
