Infuence of Method for Imposing Essential Boundary Condition on Meshless Galerkin/Petrov-Galerkin Approaches

The new meshless methods have been proposed by choosing the trial and test functions from a variety of the functional spaces. The accuracy of the proposed methods is evaluated for two imposing methods of the essential boundary conditions. The results of computations show that the type of the test functions does not influence on the accuracy. In contrast, the weight functions should not be chosen as the trial functions to ensure the accuracy
