1 MSC.Marc 2005 What s New Overview

2 MSC.Marc 2005 Functionality General Contact and Friction Improvements Table Input Global-Local Analysis Global Remeshing Updated ACIS and ITI libraries for Mentat Manufacturing Machining Phase II Pre-State Welding Parallel Adaptive Meshing Performance Scalability Improvements in Parallel Parallel Processing Single Input File

3 MSC.Marc 2005 Functionality Power Train Bolt Modeling Materials Generalized Strain Energy Shape Memory Alloys Multiphysics Thermal Enhancements Electrostatics-Mechanical Magnetostatics Enhancements Integration RBE3 Large displacement enhancements (Marc- Nastran Integration) Adams-Marc Interface Marc Preferences in Patran

4 Contact with Transformations

5 Contact Runs 2.2 Times faster With Better Control Of Separation

6 Contact Enhancements Customer Success Story: Contact with higher order elements: Magnitude and location of failure accurately predicted

7 Virtual MFG Advances Stretch & Drape Forming: New Element Technology = 40% speed up

8 Friction Modeling Improvements

9 Multivariable Table Input Improves the ease of use Increases the product capabilities Improves the accuracy by allowing continuous functions Reduces the size of the input file Minimizes the need for user subroutines Improve compatibility with CAD programs Improves compatibility with Patran and Mentat Improve compatibility with MSC.Nastran TABLE* BDF Allows parametric input (not in Mentat)

10 Table Input - Contact

11 Table Input - Contact

12 2D Table For Yield Surface The yield surface is created from two curves multiplied together

13 2D Table For Yield Surface During plastic flow every integration point must be on the yield surface (follow the red dot) The disk is cycled from cold to hot two times
