10 Meshless methods and their numerical properties
conditions may be difcult. However, various techniques of imposing the
essential boundary conditions are discussed in the work of Krongauz and
Belytschko (1996).
2.3.5 Solving assembled system of equations
The nal system of equations can be solved by either the direct or itera-
tive methods.
2.3.5.1 Direct method
There are several direct methods to solve the linear system of equations,
such as the Gauss elimination, LU decomposition, LDL
T
decomposition,
and Cholesky factorization.
2.3.5.2 Iterative method
There are also several iterative methods available, such as the Jacobi, Gauss-
Seidel, conjugate ...
