5. Company Overview 40 Years of MSC Milestones
Company founded by Dr. Richard MacNeal and Mr. Robert Schwendler. Developed first program called SADSAM (for Structural Analysis by Digital Simulation of Analog Methods) - the forerunner to MSC.Nastran
MSC participates in NASA-sponsored project to develop a unified approach to computerized structural analysis. The program became known as NASTRAN (NASA Structural Analysis Program)
A team of researchers at Brown University initiated the development of the technology leading to the MARC program
The MARC Analysis Research Corporation was founded
MSC releases proprietary version of NASTRAN, called MSC.Nastran
MARC Corp releases the first proprietary version of MARC, the first commercial Nonlinear finite element analysis program
MSC merged with PDA Engineering (Developer of PATRAN) to become the largest single provider of finite element analysis (FEA) software to the CAE market
MSC.Software merged with MARC Analysis Research to lead both the linear and the nonlinear analysis worldwide CAE market
… Continuous development of the Marc product with v2000, v2001, v2003…

6. What is MSC.Patran?
MSC.Patran is a finite element pre- and post-processor, which has been integrated with several nonlinear analysis solvers including MSC.Marc and MSC.Nastran for implicit solutions; MSC.Dytran and LS-Dyna3D for explicit solutions
Together, MSC.PATRAN and MSC.MARC are particularly useful for modeling complex non-linear problems

7. What is MSC.Patran?
Common look and feel for many analysis codes, strong CAD geometry integration, and powerful meshing and model manipulation through MSC.Patran

8. MSC.Patran Drives MSC.Marc
MSC.Patran on-line help facility includes documentation for all GUI forms and topics.
In many cases, all model definition, analysis submittal and results evaluation can be done through MSC.Patran

9. MSC.Mentat Drives MSC.Marc
In all cases, model definition, analysis submittal and results evaluation can be done via MSC.Mentat
MSC.Mentat on-line help facility includes documentation for all GUI forms and topics.

All elements support large deformations
Most elements support large strains
Many large rotation- increment shells/beams
All elements may be combined
User control over integration methods
0D (Point) Elements 1D (Bar) Elements 2D Solid (Continuum) Elements 2D Shell Elements 3D Solid (Continuum) Elements

19. MSC.Marc Advanced Solution Features: Contact
Marc tracks the motion of all contact bodies with respect to each at all times
When two bodies come into contact, Marc automatically determines the area of contact and calculates the contact normal and friction stresses
The user may also request the calculation of Normal and Friction (nodal) Forces.

20. MSC.Marc Solution Features: Local Adaptive Remeshing

21. Marc Advanced Solution Features: Global Adaptive Remeshing
Available in 2D and 3D for continuum elements

22. MARC Advanced Solution Features: Global Adaptive Remeshing
For problems exhibiting very large strains and mesh distortion – preventing the analysis from stopping
Example:
Two rubber pieces coming into contact
The piece on the left undergoes self contact as the hole closes up

23. MARC Advanced Solution Features: Distributed Domain Decomposition
Parallel Processing
Automatic Subdivision based on Metis
Manual Decomposition based on MSC.Patran Groups
Generally linear scaling for 2 to 8 processors
Use up to 64 processors
The Domain Decomposition Method (DDM) is supported in v The model is broken into domains and each domain is submitted to a separate CPU to parallel process the analysis.
The domains can be created manually by assigning a Patran group to each domain. Or you can use Metis to automatically create the domains for you.
Verification tools exists to visualize each domain and ensure that there are no duplicate entities or missing entities in any of the domains.
Multiple Marc input files are created and submitted to the master host. The master host then distributes the other input files for each domain to the proper machine. A results file from each is returned.
When MSC.Marc supports DDM within the solver, Patran will submit the job without breaking the model into domains. Rather you will just tell Marc how many domains you want and a single input file will be transferred. Marc will then use an automatic DDM (probably Metis) and submit the job transparent to the user.
