PHƯƠNG PHÁP PROPER GENERALIZED DECOMPOSITION CHO BÀI TOÁN PHI TUYẾN

In numerical approximate method, for highly exact requirement the ones often mesh space and time very smooth, which common discrete methods spend a lot of time for solving that model. This studying presents a discretization technique, the Proper Generalized Decomposition (PGD), and use its ability to solve the non-linear problem such as heat tranfer and fluid flow. Applying PGD to solve Poisson equation of the two-dimensional incompressible fluid and comparing to the Successive over-relaxation (SOR), the result show that PGD is faster than SOR about 200 times with the element number is about 10000.
