FEAview supports most MSC.Nastran™
elements, properties, materials, loads, and constraints commonly
used in linear static problems. See elements
for a list of supported elements and data types.
FEAview's post-processing and results viewing capabilities
are based on code that was heavily used in the commercial
aircraft industry.
FEAview reads binary OUTPUT2 files
produced by MSC.Nastran™ running on a Linux or a Windows
PC. FEAview can read most model files in the MSC.Nastran™
distribution. Some features are not supported (such as macros)
but, in general, FEAview is good at reading MSC.Nastran™
files -so long as it is dealing with the structures subset
that FEAview understands.
FEAview post-processing functions:
- The Max/Min process finds the
maxima of each of the variables associated with each element.
- The loadcase history process collects
the values of each of the variables associated with each
element for all loadcases.
- Computes Principal Forces and
Strain for line elements, little enhancements to
Nastran.
- Uses the raw Grid Point Force Balance
(GPFB) data to dynamically recalculate the Totals
to reflect the out-of-model forces when the original model
is reduced by a windowing operation.
Top
- FEAview has five basic data presentation
modes:
- Various tabular displays
- Color
plots
- Deformation Animations.
- Max/Min plot, a variation of freebody
plot showing the maximum and minimum loadcase number for
each variable of each element and node.
- Loadcase history plots.
- FEAview Import function:
- FEAview can import data from any program so long
as an import file is prepared using a simple, free-form
format. This data can be added to the solver data or
read in place of it.
- FEAview supports the following data types:
- Properties,
- Force,
- Principal Force (FEAview enhancement).
- Moment,
- Stress,
- Strain,
- Principal Stress or Strain,
- Displacement,
- Forces of Single Point Constraint,
- Grid Point Force Balance data,
- Reaction forces, applied forces, and temperature.
- Provides display controls for each data
type, element type, and most element variables.
- FEAview provides tables to view and/or
edit:
- properties,
- materials,
- loads,
- Inquiry functions to provide comprehensive information
about a node, element, property, or material,
- the Inquire Node function has a detail button to show
the data for those elements contributing to the dynamically
recalculated GPFB totals. (This was broken prior to version 3.0.)

FEAview contains an basic modeler that uses simple
parametric curves and surfaces rather than splines.
- The modeler creates and edits elements,
nodes, properties, materials, loads, and constraints.
- It uses various geometric constructors
(points, lines, polygons, curves, wires, surfaces, and volumes)
to build shapes and provides tools to mesh these shapes.
- All curves and surfaces are user definable
and editable function parser or Python functions.
- As delivered, FEAview provides around
100 curve and surface definitions. Most curves and surfaces
are doubly defined for Python and for the program's built-in
function parser (the Warp function parser) so you do not
need to learn Python while getting started with the program.
- Curves types:
- parametric, polar, explicit
- polyline
- Catmull-Rom.
- Surface types:
- Volume types:
- extrusion
- rotational sweep
- general sweeps of a surface along a track curve.
- lofted surfaces.
- All constructors have edit functions.
Example
- FEAview provides functions to mesh the
geometric constructors.
- FEAview provides functions to copy, move,
and delete constructors.
- FEAview can copy, move, scale, delete,
etc. elements and nodes. Example
- FEAview can read a multiple model scene
and merge the models together.
