Abstract: This poster exposes the results of a new implementation of the FE2 multi-scale algorithm that is achieved by coupling the multi-physics and massively parallel code Alya with the GPU-based code micropp. The coupled code is mainly designed to solve large scale and realistic composite material problems for the aircraft industry. Alya is responsible of solving the macro-scale equations and micropp for solving the representation of fibres at the microscopic level. The poster shows computational performance results that demonstrate that the technique is scalable for real size industrial problems and also how the execution time is dramatically reduced using GPU-based clusters.
