چکیده انگلیسی
Development of meshfree methods is in full swing in the last few decades as these methods overcome the shortcomings of mesh based methods. Development of meshfree methods for large scale problems requires fast iterative solvers. Preconditioner plays an important role in improving convergence rate of an iterative solver. Recently proposed SRJ method can be used as a stand-alone solver and as a preconditioner in CG type methods. Objective of the present work is to evaluate the performance of SRJ method as a preconditioner in BiCGSTAB method in connection with the MLPG method. Three dimensional Poisson equation and heat conduction equation are solved in regular and irregular domain respectively. The SRJ method is tested as a solver and as a preconditioner in BiCGSTAB method. Its performance as a preconditioner is compared with Jacobi and SOR preconditioners.
