Understanding the format of universal files

[FreeJBird]

Hello! I export a results envelope containing the maximum stress component to a universal file. Now I opened the universal file and I am trying to understand its format/meaning. The .unv file looks like the following snippet and my comments are proceeded by #:

-1 #I think this just signifies the start of the file
2414 #What is this?
1 #What is this?
Check #What is this?
2 #What is this?
RESULT_NAME_KEY Test1 #this name shows up in the result tres
NONE #What is this?
NONE #What is this?
Creation time 12-Feb-14 13:39:25
NONE #What is this?
1 1 1 94 2 1 #What are these numbers?
1 0 1 0 1 0 0 0 #What are these numbers?
0 0
0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 #What are these numbers?
0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 #What are these numbers?
16547 1 #The Element id, but I have no idea what the 1 is
-2.39430E+00 #the scalar cell value to displayed
16548 1
-3.37685E+02
16549 1
-7.12877E+00
...
-1 #I think this just signifies the start of the file

I need to know the format because I want to manipulate the results and I want to make sure that I do no mess anything up when I do that.
