Elimination Method for Parallelization of Flexible Multibody System Dynamics
Original language description
The paper describes a procedure for solving flexible multibody system on multiple parallel processors with special attention to the computational efficiency. The procedure combines the usage of efficient algorithms on single processor with massive parallelization with the goal to achieve improvement by parallelization even for small systems. The paper describes the extension of the elimination procedure towards the parallelized dynamic solution of flexible multibody system. The method is based on the modified state space and the efficient set of natural coordinates and modal coordinates for the description of the deformation in the system. The elimination process is solved by the efficient combination of elimination process and Cholmod procedure. The resulting computational complexity is very promising. The elimination procedure is applied only to the computation of reaction forces and the local equations of motion are solved completely independently on parallel processors without any constraints between the processors.
