Beginning with MSC NASTRAN

What is Nastan and Why is it used?

       Nastran is MSC high end solver. Earlier there was no software like Patran to create Structure Condition and Engineers would type text files known as decks/input files/.bdf/.dat and that would contain all the FEM information of your model that needs to be solved.

       Now we use Patran or Altair HypreMesh  to make these input files. Patran would write a .bdf, send it to MSC Nastran to have solve, MSC Nastran makes result files, and then Patran imports the results for post processing.

       Understand these input codes are necessary in order to handle FEA problems. These codes are the language Nastran uses to solve the problem.
