using rosouttaberria.tk and rosouttaberria.tkn. It is provided to be a supplement MSC. Nastran features. However, it should serve as a starting point for. Instruction Based Patran/Nastran Tutorials. - Computer Labs at Builds Confidence in Value of Method. Tutorial 1. Double-Cantilevered Bar. Tutorial 2. Truss. Y. rosouttaberria.tk Where can I find a nastran topometry optimization tutorial? Question.
Nastran SOL? What is MSC. Allows Nastran users to perform: advanced nonlinear structural analysis Includes contact, large deflection, large rotation, and large strain analysis capabilities never before available in Nastran Can use input decks from the many thousands of existing MSC.
Nastran models. Provides solutions for simple to complex engineering problems including multibody contact and advanced elastomeric rubber material models 5 How Does MSC. Nastran SOL Work?
How Does MSC. MARC Mature Robust Nonlinear Algorithms provide: A powerful tool for simulating manufacturing processes and component behavior multi-body contact analysis capability much easier to set up long list of advanced material models and element technology robust solutions for solving complex contact and load history problems for a wide variety of problems 7 How Does MSC.

Check the written report of the truss results. The file containing the written results from the analysis is scaled truss.
Open the file by simply double clicking on it. The file might be in the root or home directory or in the directory from which you ran the analysis.
In this file find the displacement vectors and record the numerical values.
These will help you answer some of the question below. Also, find the vectors for the stresses and constraint forces and record these values. Also, information from the output file truss. As used below, the term "member" refers to the portion of a truss structure between two joints. For example, the top of this structure has two horizontal members which are connected by the joint at which the load is applied.
What is the maximum displacement for the structure? Is this displacement consistent in location, magnitude and direction with your physical intuition? What is the maximum stress in the structure?
Is this stress consistent in location, magnitude and direction with your physical intuition? Are there any members with very low stresses? Does this make physical sense?
How many equations are solved in order to determine the displacements for this structure? What assumptions are involved in using this specific element as opposed to using a 2 node beam element with 6 degrees of freedom 3 displacements and 3 rotations per node?
The present model uses a single 2-node bar element for each truss member.
Would the accuracy of the model increase if two bar elements were used to model each truss member? Justify your answer.
The resultant forces sometimes called constraint, restoring or reaction forces , are located at the nodes where the boundary conditions are applied. State how these resultant forces can be used as a "necessary but not sufficient" test of the accuracy of your analysis.
