34 CHAPTER 3. COMMAND DESCRIPTION
3.9.1 *PDIS: Calculating displacement at a given point
Command *PDIS, suboption of *PARAMETER command, for evaluating the displacement at
a defined degree of freedom for a given point.
The following parameters are required:
INPUT Set INPUT=COORD (point for calculating the displacement
is given by the coordinates), INPUT=NODE (point
is defined as a finite element node)
NAME Set this parameter equal to the name of the displacement,
for example, NAME=CTOD.
Format Entry
If INPUT=COORD the following data lines are required:
I, 3F Degree of freedom, X,Y,Z.
Repeat the above line as often as needed to give the more points.
If INPUT=NODE the following data lines are required:
DOFN, NODE Label
. . .
2I Degree of freedom, Nodal label.
Repeat the above line as often as needed to give the more points.
Examples:
1. Use the following entries to calculate the nodal displacement U1 at the point (100.0, 100.0,
0.0) and U2 at the point (0.0, 100.0, 0.0).
*PDIS, INPUT=COORD, NAME=LOAD
1,100.0, 100.0, 0.0
2,0.0, 100.0, 0.0
