Powerful Solver CapabilitiesANSYS structural mechanics solutions offer a large library of out-of-the box equation solvers. The library contains the sparse direct solver, the preconditioned conjugate gradient (PCG) iterative solver, the Jacobi conjugate gradient (JCG) solution, etc. In addition, the distributed versions of PCG, JCG, and sparse solvers are available for use in large-scale computing via parallel processing. By combining our parallel algorithms with the power of GPUs you can further reduce the solution time required for your large models. Variational technology from ANSYS allows acceleration of the computation of normal modes for cyclic structures, especially when a large number of harmonic indexes are required. Frequency sweeps such as those found in harmonic analyses also benefit from variational technology. Typical speedup factors observed range from three to 10. Transient thermal runs and certain classes of nonlinear structural transient problems are computed in a shorter time using these same principles.
Multiple GPUs can be used on nodes of a cluster to reduce computing time. For example, solder balls were modeled with 4M DOF for creep strain analysis. Results courtesy MicroConsult Engineering, GmbH. |
