Multidisciplinary Structural Analysis
MSC's flagship product. In a field where unreliable results can cost enormous amounts of money, MSC Nastran has been proving its accuracy and efficiency for more than 40 years. As it continually evolves, it accumulates the advantages of the latest techniques and algorithms, and therefore remains the best finite element analysis system in the world.
World leaders in advanced mechanical engineering are using MSC Nastran as a versatile finite element system for modeling and design optimization. The highest level of functionality, reliability and performance has kept the MSC Nastran system at the forefront of the world for more than 40 years. MSC Nastran is used to develop the most advanced aviation, automotive, aerospace, high-tech devices and structures in other technical fields. Versatility and versatility, combined with high computational efficiency and open software architecture, allow engineers to perform complex, comprehensive, multidisciplinary design calculations in a single environment.
MSC Nastran provides a complete set of calculations, including calculation of stress-strain state, safety margins, natural frequencies and vibration shapes, stability analysis, investigation of steady and unsteady dynamic processes, solution of problems of heat transfer, acoustic phenomena, nonlinear static and nonlinear transient processes, analysis of complex contact interaction, calculation of critical frequencies and vibrations of rotor machines, analysis of frequency characteristics under influence of random loads and pulse broadband
Software allows to develop a new or inspect and check existing design of different parts and systems.
MSC Nastran is based on proven finite element technology and robust numerical methods. As a result of years of optimization and testing on a variety of problems, MSC Nastran delivers the highest computational speed.
MSC Nastran allows the simulation of a wide range of materials, both isotropic and anisotropic, linear and non-linear, that may be strain dependent, temperature dependent, strain rate dependent, etc. MSC Nastran widely uses beams, shells, volume finite elements, as well as special elements for modeling point and seam welding, bolted and riveted joints, “rigid” elements of various types (kinematic links between the nodes of the calculation model), interpolating links and much more.
Extended functions of MSC Nastran include methods of static and dynamic condensation of computational models, model synthesis and Craig-Bampton method. The superelement method allows to consider complex products in parts, transfer computational models of substructures in matrix form between departments and enterprises while preserving the confidentiality of the original model, with the possibility to output the results for all nodes and elements of the model. The MSC Nastran superelement technology is the de-facto standard in international mechanical engineering cooperation. The use of this technology allows participants to exchange product models, while maintaining confidentiality of internal dimensions, properties, materials, part connection methods, etc.
MSC Nastran has a powerful automatic structural optimization tool for statics, stability, steady-state and unsteady-state dynamic processes, natural frequencies and waveforms, acoustics, and aeroelasticity. Optimization is carried out on the basis of selected calculation types by varying the shape parameters, dimensions, and properties of the structure. Due to their efficiency, the optimization algorithms handle an unlimited number of design parameters and constraints. Weights, stresses, displacements, natural frequencies and many other characteristics can be treated either as design target functions (in which case they can be minimized or maximized) or as constraints.
MSC Nastran provides the ability to calculate the performance of composite structures. Especially effectively these possibilities are realized when using MSC Nastran in combination with a special option of Patran software package – Patran Laminate Modeler, providing fast preparation of highly accurate finite-element models of composite structures and effective processing of results.
The close coupling of MSC Nastran with Patran provides a fully integrated environment for modeling and analyzing results. All leading manufacturers of pre-, post-processors and CAD systems, recognizing the indisputable leadership of MSC Nastran in the finite element market, provide direct interfaces to the system.
As a part of MSC Nastran there are special solution sequences SOL 600 and SOL 400, focused on solving problems of analysis of significantly nonlinear behavior of the product, multidisciplinary analysis, as well as problems of calculation of sequential loading of the product by influences of different nature (heat – strength, etc.).
MSC Nastran SOL 600 is essentially a Marc solver “built in” to MSC Nastran. The advantage of using SOL 600 is that you can access the effective tools of the Marc solver while working within the structured MSC Nastran interface, which is familiar to a huge number of users. MSC Nastran solutions using SOL 600 run efficiently on multi-processor computer clusters.
MSC Nastran SOL 400 is a further development of the MSC Nastran solver in terms of enhancing the efficiency and accuracy of solving static and dynamic problems, improving the algorithms for 3D contact interactions between the parts of the calculation model, introducing new algorithms for thermal problem solving (algorithms used in the Sinda software package), expanding the capabilities for solving multidisciplinary problems by combining different types of analysis (e.g. thermal calculation – static – dynamic) into a single calculation case for a comprehensive investigation
The MSC Nastran software package includes the SOL 700 solution sequence, which combines the capabilities of the well-known LS-DYNA and Dytran solvers and is designed mainly for modeling high-speed loading of products, including their large deformations and destruction (for example, collisions of various objects, technological processes like stamping, forging etc.), and dynamic interaction of a product and a gas or liquid medium (for example, interaction of an airbag and a dummy in a car collision etc.). SOL 700 uses a highly efficient explicit integration scheme to solve nonlinear problems. By integrating LS-DYNA and Dytran solvers into MSC Nastran, the time required to prepare a computational model is reduced and the accuracy of multidisciplinary analysis is improved.
The computational performance of MSC Nastran is optimized to handle large and ultra-large problems, as well as complex, related types of multidisciplinary analysis, in line with current trends in virtual modeling technology and customer requirements.
