A truly meshless Galerkin method is formulated in the present study, as a special case of the general Meshless Local Petrov-Galerkin (MLPG) “Mixed” approach. The Galerkin method is implemented as a truly meshless method, for solving elasto-static problems. In the present Galerkin method, the test function is chosen to be the same as the trial function, as a special case of the MLPG approach. Ho...

A Fourrier Petrov Galerkin spectral method is described for high accuracy computation of linearized dynamics flow in a circular pipe. The code used here based on solenoidal velocity variables. It written FORTRAN. Systematic studies are presented the dependence eigenvalues and other quantities axial azimuthal wave number; reynolds’ number Re new none-dimensional Ne. will be considered stable if ...
