Titolo: MSC.Nastran

Ciao a tutti,
qualcuno di voi potrebbe gantilmente indicarmi un sito da cui scaricare un
manuale o una guida o un tutorial, per imparre ad utilizzare l'MSC.Nastran.
Per chi non lo conoscesse è un programma di analisi agli elementi finiti,
molto utilizzato nel campo dell'ingegneria meccanica. Mi sarebbe utile anche
l'indirizzo di una buona libreria tecnica, per acquistare un manuale qualora
non riuscissi a trovare nessun sito utile o se non dovessi incontrare
nessuna anima pia che mi possa dare una mano. Ringrazio anticipatamente
tutti per l'attenzione prestatami e per l'aiuto. A buon rendere
SAX

di solito quando acquisti il programma ti danno tutta la documentazione....

e questi:
CalculiX for linear, non-linear static & dynamic analysis, uses only 3D 
tetrahedron & hexahedral elements. Hyperelastic, plastic & user defined 
materials. Creep analysis. This is an open-source project.
MyStran is a general purpose finite element analysis computer program 
for structures that can be modeled as linear. In this free solver, many 
structural analyses modeled for execution in NASTRAN will execute in 
MYSTRAN with little, or no, modification.
Impact is an open-source (Free) explicit solver for modelling dynamic 
phenomena such as car crashes, usually involving large deformations.
GiD This is a low cost Pre & Post processor. The free Academic Version 
of GiD is completely functional but meshes are limited to only 700 2D 
elements or 3000 3D elements.
Z88 is GNU-GPL Freeware. It features 20 finite element types covering 
plane stress, plate bending, axial symmetric structures and spacial 
structures up to 20-node Serendipity hexahedrons. Z88 comes with a 
user-friendly interface, a powerful mesh generator, a DXF-converter, a 
plot program and two powerful solvers. Import of COSMOS files from 
Pro/ENGINEER and Pro/MECHANICA is supported.
FEAPpv is a general purpose finite element analysis program which is 
designed for research and educational use. It is described in The Finite 
Element Method by OC Zienkiewicz and RL Taylor.
LISA can be used for linear static & dynamic stress analysis, eigen, 
steady/unsteady heat
transfer, incompressible fluid flow, seepage, electromagentic, acoustic 
analysis, etc. 1300 node limit on free evaluation version.
UNA is a solver that can be used with systems such as FEMAP, PATRAN, 
I-DEAS and , NASTRAN. The solver can be used for static analysis, modal 
analysis, elastic buckling, substructuring, transient response, 
frequency response, random vibrations, aeroelastic response. It is a 
sparse linear matrix solver, sparse Lancos eigenvalue solver. 
Automatically eliminates local singularities, etc. Limited to 20,000 
nodal degrees of freedom.
JL Analyzer A fully functional, free FEA system limited to 300 nodes. 
The complete analysis package includes pre/post process operations and 
all analyses such as static, dynamic, buckling, frequency, thermal, 
electric and more.
FesaWin is a 3-D Finite Element Stress Analysis program. It includes 
beam, membrane and plate bending elements, there is a 100 node limit in 
the free version.
Analysis for Windows calculates two and three dimensional Truss and 
Frame behaviours using the Finite Element Method.
CMISS is a mathematical modelling environment that allows the 
application of finite element analysis, boundary element and collocation 
techniques to a variety of complex bioengineering problems. Runs on SGI 
IRIX 6.5 and above.
FELIPE is a low-cost finite element software package, running under 
Windows 95/98/NT/2000 or later, developed to support students of 
mathematics or engineering in understanding, appreciating and using the 
finite element method. Because it contains a powerful pre-processor and 
post-processor, as well as source code for the main engines, it also 
enables more experienced finite element practitioners to develop FE 
analyses of their individual problems, for research or commercial 
purposes. Free download for evaluation purposes.
FRANC2D is a finite element based simulator for curvilinear crack 
propagation in planar (plane stress, plane strain, and axisymmetric) 
structures.
FRANC2D/L is a highly interactive finite element program for the small 
deformation analysis of two-dimensional structures. It is useful for 
engineering calculations or for instruction in finite element and 
fracture courses. Linear elastic fracture mechanics analyses can be 
performed with automatic remeshing as the crack grows. The layered 
capability allows the user to model riveted and adhesively bonded 
structures, such as lap joints and bonded repairs. Elastic-plastic 
material behavior is also available
FRANC3D is a work-station based FRacture ANalysis Code for simulating 
arbitrary non-planar 3D crack growth. It has capabilities for modeling 
multiple, non-planar, arbitrary shaped cracks, where the cracks can be 
surface cracks, internal cracks, cracks in material interfaces, cracks 
cutting across material interfaces, intersecting cracks, and even 
complete discontinuities.
FEMM is free FEA software for magnetic field analysis. It can solver 2-D 
planar and axisymmetric magnetic problems (including linear and 
nonlinear magnetostatic problems and linear low frequency harmonic 
problems).
MagSolve is an interactive suite of programs which allows the solution 
of 2-D static magnetic field problems by the Finite Element Method. The 
programs include features for geometry input, automatic FE mesh 
generation, solution and analysis of the solution. The programs are 
written to run on UNIX / X-Windows systems.
QuickField package for electromagnetic, thermal, and stress design 
simulation with coupled multi-field analysis. The free version has a 
limited size finite-element mesh.
OOF helps materials scientists to calculate macroscopic properties from 
images of real or simulated microstructures. It reads images in the ppm 
(Portable Pixel Map) format and assigns material properties to features 
in the image and conducts virtual experiments to determine the 
macroscopic properties of the microstructure. Currently, the programs 
calculate stresses and strains.
Code Aster is a French open-source FEA system. Linear & non-linear 
static/dynamic, thermal & fluid analysis, unfortunately not in English.
