Import/Export
CAD Geometry
Enables
import geometry from leading CAD systems for creating finite
elements models. Access of IGES files from any CAD system:
geometric entity types can be points, curves and surfaces.
Finite elements entity types can be accessed including
nodes, elements and transformation matrix. Export IGES
files includes geometry and finite elements entities.
Display 3D Model
- Mouse control in 3D real time thanks to OpenGL graphics card
accelerator
- Full OpenGL
- Display 3D model, in wireframe, shading, smooth shading,
and textured shading.
- Display 3D FEM (Finite element model) in different mode such
as: wireframe, element shading, shrink element shading,
distortion, warping, sizing elements shading
- Hide and show 3D parts on screen with fast processing
General Meshing Features

between points or nodes, curves ends, curves parameters, circle
center in different coordinates systems.
- Creating elements by nodes selecting or by lower order elements
- Translate, rotate, sweep, edges 1D elements to create 2D
elements.
- Translate, rotate, sweep, 2D elements to create 3D elements
- Manipulate or create elements by copy translation, copy rotation,
copy mirror
- Modifying element, such as quadrilateral to triangles and
invert, reverse normal, extend edges elements, cut and paste
elements, color, level, etc.

Graphical
User Interface
Console
keyboard-based and mouse-driven menu system for the operation
of all tasks. It is designed to be intuitive, easy to learn and
use. Based on Qt Trolltech® framework GUI is
compliant with OSF Motif standard on Unix platforms, Microsoft
Windows and MAC OS platforms. GUI allows user input from the
mouse or keyboard.
Thanks to powerful graphics selection engine various selection
modes are available like as both "drag-box" and "polygon" picking.
Identification of entities by labels or by cursor picking with
highlighting.
For geometries, selection can be done by single or multiple screen
entity, color, level, type and boolean operations on different
attributes.
For FE selection can be done by single or multiple screen entity,
free faces, free edges, properties, boundaries conditions, coordinates
systems. and boolean operations on different FE attributes.
Commands
interrupt capability.
Automatic Mapped Meshing
- Quadrilateral and Triangle element meshing
- Create and manipulate Mapped Mesh Areas
- Modifying element, such as quadrilateral to triangles and
invert, reverse normal, extend edges elements, cut and paste
elements, color, level, etc.
- Defining elements size or number of elements on edges, with
biais or not
- Automatic edges selection for creating Mesh Areas

mesh density controls including curvature check
Loads sets
- Allow user to create and manage many loads sets
- Mechanical or Thermal loads sets can be defined (heat, Temperature,
Nodal force, pressure, acceleration, etc.)

conics, 3D Bezier and Nurbs curves and surfaces
- Geometry based on different levels (layers), groups and colors
- Creating and modifying 3D Bezier or Nurbs curves by polygon,
interpolation, extrapolation, convert graphics entity to 3D
Bezier or Nurbs, intersection of surfaces, blend with tangent
or curvature on edges or ends curves,
- Project curve on surface
- Modifying curves by points polygon control, change degree
and knots vector.
- Divide curve on point
or parameters, merge curve, move ends, blend ends
3D Automatic Free Meshing for Solid
- Tetrahedral element meshing
- Automatic tetrahedral element meshing on general solid defined
by surfaces (Boundary representation)
- Extensive user-defined and automatic mesh density controls
including curvature checks to rapidly create optimum mesh models
