40 CONTINUE
C
50 NVAL = NVPN*NNODS
Where: NUM Is Element Number.
NVAL Is Number Of Real Or Complex Data
Values For This Element.
VAL Is Real Or Complex Data Array.
7 Data Characteristic Values Imply The Following Values
Of NDV:
Scalar: 1
3 DOF Global Vector: 3
6 DOF Global Vector: 6
Symmetric Global Tensor: 6
General Global Tensor: 9
8 Data On 2D Type Elements May Have Multiple Values
Through The Element Thickness. In This Case, NVAL =
NDV*NPOS*NNODS Where NPOS Is Number Of Positions
Through Element And NNODS Is Number Of Nodes On
Element. The Order Of Data Is NDV Values For
Position 1 Of Node 1,NDV Values For Position 2 Of
Node 1, . . . , NDV Values For Position 1 Of Node 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 Records 9 And 10
Appear, 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 Integer 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.
12 Dataloaders Use The Following ID Line Convention:
a. (80A1) Model Identification
b. (80A1) Run Identification
c. (80A1) Run Date/Time
d. (80A1) Load Case Name
