NOTES:
1 ID Lines May Not Be Blank. If No Information Is
Required, The Word "None" Must Appear In Columns
1-4.
2 For Complex Data There Will Be 2*Nval Data Items. The
Order Is Real Part For Value 1, Imaginary Part For
Value 1, Real Part For Value 2, Imaginary Part For
Value 2, Etc.

X, Y, Z
Rx, Ry, Rz
Symmetric Global Tensor:
Sxx, Sxy, Syy,

4 ID Line 1 Always Appears On Plots In Output Display.
5 If Specific Data Type Is "Unknown," ID Line 2 Is
Displayed As Data Type In Output Display.
6 Typical Fortran I/O Statements For The Data Sections
Are:
READ (LUN, 1000) NUM, NVAL
WRITE
1000 FORMAT (2I10)
READ (LUN, 1010) (VAL(I),I=1,NVAL)
WRITE
1010 FORMAT (6E13.5)
Where: NUM Is Element Number
NVAL Is Number Of Real Or Complex Data Values
For This Element (Max = 90)
VAL Is Real Or Complex Data Array

Of Ndv:
Scalar: 1

8 Data On 2d Type Elements May Have Multiple Values
Through The Element Thickness. In These Cases,
NVAL = NDV*NPOS Where NPOS Is Number Of Positions
Through Element. NPOS Is Always 1 For Solids. The
Order Of The Data Is NDV Values For Position 1, NDV
Values For Position 2, Etc. The Order Of The Nodes
Defines An Outward Normal Which Specifies The Order
From Position 1 To NPOS.
9 Any Record With All 0.0's Data Entries Need Not (But
May) Appear.
10 A Direct Result Of 9 Is That If No Record 9 & 10
Appears, All Data For The Data Set Is 0.0.
11 When New Analysis Types Are Added, Record 7 Fields 1
And 2 Are Always > Or = 1 With Dummy Interger And
Real Zero Data If Data Is Not Required. If Complex
Data Is Needed, It Is Treated As Two Real Numbers,
Real Part Followed By Imaginary Point.
