Performance Improvements
New Parallel Solvers Deliver Better Performance for
Nonlinear Problems
Users can now take full advantage of multi-core machines for parallelization. Significant benefits in performance are obtained at no additional software costs. The Marc multi-frontal solver now utilizes multi-threading on Windows and Linux based shared memory architectures. The Pardiso solver utilizes parallelism in a shared memory Windows and Linux environment and the MUMPS solver may be used in both a shared or distributed memory Windows and Linux environments. This provides cost effective solutions for large simulations.
"Using the Domain Decompositions Method (DDM) in combination with the new parallel solver capabilities, we have seen excellent scalability in a distributed multi-processor environment. A 300,000 DOF thermo-mechanical creep analysis of a ball grid array is analyzed 7.1 times faster with DDM on a 32-core system compared to a single CPU run, while 700,000 DOF model is run 13.6 times faster," said Sanjay Choudhry, VP Product & Release Management at MSC.Software. "This greatly improves throughput and allows an increase in the number of designs that can be evaluated."
Functionality Improvements
Contact Enhancements Improve Accuracy
A new procedure for contact based on segment-to-segment and surface-to-surface is now available. These methods provide efficiencies for assembly modeling and interference fit problems. Users can expect to see more accurate and smoother results especially near contact boundaries.
New Material Models Help You Simulate New Classes of Materials
Two new material models are added in this release to increase the accuracy of simulations. The exponential cap model may be used to model granular materials like powder metals, ceramics, and soils. The 5th order Mooney model may be used for rubber analysis. These models have applications in several industries including automotive, packaging, energy, biomedical industries, and civil engineering.
Large Deformation Enhancements Improve Convergence
Updated Lagrange analysis is improved to handle large shell and beam rotations more accurately and with improved convergence. This enhancement is beneficial for Marc users who deal with large deformation and large rotation problems.
Fracture Mechanics Enhancements Provide More Control
Enhancements have been made in the VCCT capabilities which may be used to predict both crack onset and crack propagation. Two user subroutines are also added to give users more control on simulating delamination in composite parts.
Global Adaptive Meshing Increases Efficiency
Global adaptive meshing now works with two additional features, global-local analysis and the Exclude option. Users can now make better use of global remeshing in complex contact situations. Another significant enhancement is support for DDM, giving users the ability to solve larger models that undergo large deformation and need remeshing for better results, like in 3-D seals and metal forming.
Wear Improvements Speed Solution
Users will now see more accurate calculation of wear especially for deformable-deformable contact. Benefits include a faster solution, more accurate results, and the ability to associate wear with contact bodies.
Multiphysics Enhancements for Evaluating More Designs
Marc has extended its
multiphysics capabilities to solve coupled magnetostatic-thermal and magnetostatic-structural problems along with the ability to simulate electrical windings and thin laminations of thin magnetic sheets. Check out the on-demand webcast below for more details.
