2.2.6.4. Typical Postprocessing Operations
Option: Display Deformed Shape
Use the PLDISP command to display a deformed shape (Main Menu> General Postproc> Plot Results>
Deformed Shape). The KUND field on PLDISP gives you the option of overlaying the undeformed shape
on the display.
Option: List Reaction Forces and Moments
The PRRSOL command lists reaction forces and moments at the constrained nodes (Main Menu>
General Postproc> List Results> Reaction Solu).
To display reaction forces, issue /PBC,RFOR,,1 and then request a node or element display [NPLOT or
EPLOT]. (Use RMOM instead of RFOR for reaction moments.)
Option: List Nodal Forces and Moments
Use the PRESOL,F (or M) command to list nodal forces and moments (Main Menu> General Postproc>
List Results> Element Solution).
You can list the sum of all nodal forces and moments for a selected set of nodes. Select a set of nodes
and use this feature to find out the total force acting on those nodes:
Command(s):FSUM
GUI: Main Menu> General Postproc> Nodal Calcs> Total Force Sum
You can also check the total force and total moment at each selected node. For a body in equilibrium,
the total load is zero at all nodes except where an applied load or reaction load exists:
Command(s):NFORCE
GUI: Main Menu> General Postproc> Nodal Calcs> Sum @ Each Node
The FORCE command (Main Menu> General Postproc> Options for Outp) dictates which component
of the forces is being reviewed:
- Total (default)
- Static component
- Damping component
- Inertia component
For a body in equilibrium, the total load (using all FORCE components) is zero at all nodes except where
an applied load or reaction load exists.
Option: Line Element Results
For line elements, such as beams, spars, and pipes, use ETABLE to gain access to derived data (stresses,
strains, and so on) (Main Menu> General Postproc> Element Table> Define Table). Results data are
identified by a combination of a label and a sequence number or component name on the ETABLE
command. See the ETABLE discussion in The General Postprocessor (POST1) in the Basic Analysis Guide
for details.
Option: Error Estimation
