Recently, meshless method, which needs nodal data only as input data, is widely noticed of its significance. The authors have recently applied one of meshless methods, Free Mesh Method (abbreviatred hereafter by FMM), to the elastic-plastic large deformation problem. FMM proposed by Yagawa et al. has some similarities to the conventional FEM, where the tentative triangular element are created around the node. This paper describes the formulation and implementation for FMM in parallel computational environment using PVM (Parallel Virtual Machine) communication architecture designed for PC clusters. Funthermore, FMM can utilizes the remesh algorithm, since FMM is based on Node-by-Node concept. The present paper will confirm effects of remeshing algorithm to improve accuracy of numerical solutions as an example of largely deformed shear block.
