Summary

This paper deals with the numerical determination of the stress and displacement distribution in a solid body subjected to the applied external force. The tackled solid mechanics problem is governed by the Navier-Cauchy equation that describes the deformation within the solid body through the displacement vector field. To obtain the solution, a coupled system of non-linear Partial Differential Equations (PDE) of second order has to be solved. In this paper, the problem is approached by a strong form Moving Least Squares (MLS) based numerical discretization also referred to as a Meshless Local Strong Form Method (MLSM). A generic C++ implementation of a MLSM is used for demonstration of parallel solution of a Point Contact problem on Intel® Xeon Phi™ multicore accelerator. All tests are executed on either the host machine with two Intel® Xeon® E5-2620 v3 6 core processors or offloaded to its 60 core Intel® Xeon Phi™ SE10/7120 series. The shared memory parallelization is implemented through an OpenMP API.
