Program to read binary results (FNO)

Hi,

The results of a Nastran analysis are written to a binary file (the .FNO file). Do any users have a program to read the binary results file (.FNO) that they would be willing to share with the group? It could be a simple program that just converts the file to a text format, or a more sophisticated program that converts selected parts of the results file and/or does manipulations on the data.

For example, imagine a transient response analysis with 100 time steps. It is tedious to review all of the results manually. A program would more quickly allow these types of things to be done:

find the highest stress at each time step.
find all of the nodes or elements with stresses above some value for each time step
sum the reaction force at the constraints at each time step.

Before I start work on such a program, I thought that I would ask first. (Also posting to the In-CAD/Inventor Nastran forum.)

Maybe the parameter RSLTFILETYPE or other Output Control Directives can be helpful here.
