FER/Solid - A finite element program of solid and structure mechanics interfaced
with CAD programs
The
program FER/Solid can be
interfaced with other finite element software or CAD programs. The main features
include:
- CAD to FEA.
- only nodes and elements are necessary for preprocessing.
- friendly GUI - Graphical User Interface
- easy operation about the definition of material properties, selection of nodes, elements, boundary lines or surface elements for the definition of boundary conditions.
- static linear and non-linear stress analysis of 2D or 3D solids and
structures.
- modal analysis (natural frequencies and mode shapes) of
structures.
- powerful postprocessing.

The
following figures illustrate the link between FER/Solid and Pro/Engineer (as an example). Three general steps are
performed for a typical stress analysis.
- Preprocessing :
The model geometry and the mesh are created by Pro/Engineer. Then, FER/Solid
imports directly the model (Figure 1). It allows you to define the
element types, element real constants and material properties.
- Solution : We
apply loads and boundary conditions to the selected groups (nodes, elements)
and obtain the solution (static or modal solution). (Figure 2)
- Postprocesing :
Results display and presentation with a powerful postprocessor (see also
FER/View
).
