\(hp\)-meshless cloud method. (English) Zbl 0893.73077
Summary: A methodology to build discrete models of boundary value problems (BVP) is presented. The method is applicable to arbitrary domains and employs only a scattered set of nodes to build approximate solutions to BVPs. A version of moving least-square interpolation and collocation method are used to discretize BVP equations, which results in a truly meshless method (i.e. without a background mesh of integration points). \(h\)- and \(p\)-adaptive strategies are tested and very good convergence of the method was observed. Several engineering applications of the method are presented.
