This book systematically introduces the moving particle semi-implicit(MPS) method and its im
provements in the mechanical engineering. The book is composed of six chapters. The first chapter in
troduces the classification of mesh and meshless methods. The second chapter carefully describes the

troduces the classification of mesh and meshless methods. The second chapter carefully describes the
derivation of the MPS method. Chapter three reviews the different wall boundary conditions used in the
MPS method and emphasizes the polygon wall boundary condition that is an important wall boundary
condition widely employed in the industry simulations. Chapter four to six introduces the latest enhance
ments of the polygon wall boundary conditions in the particle number density and the pressure distribu
tions
The book has clear structure and pays attention to the basic theories and derivations. Many newest
research progress of the MPS method are included. The book can be used as the textbook for the post-
graduate students in the field of the mechanical engineering, nuclear engineering, naval
ocean engineering and other relative majors. The researchers and engineers can also study the methods in
the book to conduct industry simulations
