MSC Nastran 기능:

Multidisciplinary Structural Analysis

Common structural analysis solutions are dedicated to one or a few analysis disciplines. To build up a comprehensive level of engineering analysis capability, multiple software solutions must be acquired, and users must be trained with each new tool. MSC Nastran features multiple analysis disciplines, enabling customers with one structural analysis solution for a wide variety of engineering problems.

• Use one platform to perform linear or nonlinear analysis for the following disciplines: static, dynamic (NVH & Acoustics included), thermal, and buckling, and reduce the dependency on multiple structural analysis programs from various vendors
• Perform fatigue analysis with embedded fatigue technologies and reduce the time usually associated with fatigue life determination
• Assess the behavior of advanced composites and fiber reinforced plastics with built in Progressive Failure Analysis and User Defined Services for Mean-field Homogenization coupling with Digimat

Customer Testimonial

"MSC’s integrated solution for linear and nonlinear calculations facilitates reuse of models which saves a lot of time in pre- processing and enables us to standardize the data exchange formats for body models when collaborating with other departments or external suppliers.”

PSA Peugeot Citroën. PSA Peugeot Citroen Selects MSC Nastran as Its Choice for Nonlinear FEA.

"MSC Nastran is used to perform both linear and nonlinear stress analysis along with dynamic analysis for various components and sub-assemblies constituting the pump. […] Accurate predictions during these simulations is helping the C.R.I. Pumps' R&D team to reduce physical testing and product development time. The simulations are also enabling our engineers to analyze more design variants and come up with optimal designs, thus saving material cost too.”

Structural Assembly Modeling

One structural member is rarely analyzed independently. Structural systems consist of numerous components, and must be analyzed as a whole. MSC Nastran features a number of methods to join multiple components for system level structural analysis.

• Expedite meshing with Permanent Glue, enabling you to connect incongruent meshes that would traditionally require time consuming mesh transitions
• Save time constructing assemblies that consists of welds or fasteners via specialized connector elements
• Use "Modules" to combine and manage multiple components of a structure and form a complete assembly without the need to use additional connection elements or worry about the ID numbering schemes.
• Speed up the re-analysis of large assemblies by constructing Superelements, and optionally, share Superelements with other manufacturers while concealing confidential design information
• Perform contact analysis and determine contact stresses and contact regions in multi-component designs
• Increase productivity by using the Automatic Contact Generation feature to automatically create the contact bodies and define the contact relationship between them

Customer Testimonial

"The use of glued contact for assemblies reduces the problem setup time from 1 day to 1 hour and avoids tedious mesh alignment between parts.”

- Julien Rodess, Study Engineer Sogeti

Automated Structural Optimization

Design optimization is a critical element in product development, but is often very iterative and requires a great deal of manual effort. MSC Nastran includes optimization algorithms that automatically seek optimal configurations in an allowed design space.

• Optimize for stress, mass, fatigue, etc. while varying design variables such as material properties, geometric dimensions, loads, etc.
• Enhance the shape or profile of structural members with shape optimization
• Find optimal composite laminate ply thicknesses with topometry optimization
• Determine optimal bead or stamp patterns for sheet metal parts with topography optimization
• Remove excess and unnecessary volume with topology optimization
• Simultaneously optimize multiple models across disciplines with Multi Model Optimization

Customer Testimonial

"Advanced optimization processes are used on both component and system level to explore the design space in search of optimal designs. MSC.Nastran & Optimus software play herein an important role to capture the simulation process and accelerate the optimization schemes.”

High Performance Computing

Analysis models can be very large in size, requiring an extended period of time to solve. Such models can take hours or days to solve with traditional FEM applications. MSC Nastran features a number of High Performance Computing capabilities enabling engineers to solve large problems fast.

• Take advantage of multi-core and multi-node clusters with parallelization technologies: Shared Memory Parallel and Distributed Memory Parallel
• Accelerate simulation time and obtain higher performance for large models using the Automatic Solver Selection feature. MSC Nastran can automatically select the optimal solver and the most efficient parallelization method to use based on the analysis specifications (element types, solution type, available memory and etc).
• Utilize nVidia GPU Cards to accelerate the analysis of models composed of solid finite elements
• Perform modal analysis faster by using a highly tuned Lanczos solver or Automated Component Modal Synthesis

"Our ability to quickly and thoroughly evaluate many design alternatives made it possible to increase the processing speed of the machine by 50% while reducing vibration levels below the previous generation of machines. [...] The first prototype provided the performance and functionality predicted by the simulation so it became the final product. The new machine was completely designed in one and a half months, faster than any similar machine.”
