Fedem Technology launches release 4.0

Fedem Technology launches the 4th generation of it's integrated simulation software. The new release confirms Fedem Technology’s strong commitment to the mechanical industry by delivering state of the art solutions for concept investigation and virtual verification of mechanical products - spanning from hand-held tools to complete vehicles.

Together with a CAD and FE-Meshing software, Fedem release 4.0 forms a complete engineering platform for mechanical product development and verification.

Fedem can be used from the early stage motions dynamics, where only hardpoints are known, to advanced models with true flexibility and advanced joint characteristics. The principal hardpoint model can use VRML geometry models for visualizaton. Finite element meshes represent parts where flexibility is crucial or stresses need to be investigated. In the early stage product development and late stage product maintenance, Fedem will provide important answers and knowledge in the continued efforts to create better and more competitive products.

Key Features new in Fedem R4.0

Faster & simplified event modeling

• A new, faster and more flexible method for combining system variables, functions and control systems.

• Sensors, Engines and Functions has been merged into a single new and intuitive Function object.

• Output from a function can be used as argument in a another function, enabling superior modeling flexibility.

Enhanced joint design

• Extended set of constraints for joint DOFs gives more flexible definition and modification of the joint type and characteristics. With the new features the detailing level of the joints can evolve along the development of your model.

• Loads can now also be applied at joint DOFs, which is extremely useful when modeling motors, actuators, hydralic cylinders etc.

• The revolute joint can be  extended into a cylindrical joint.

• A new joint type, Axial Joint, acting, enables fast and easy modeling of cylinders etc. This is a single DOF joint and  has the same constraint options as other joints DOFs.

• Spring- and damper characteristics can now also be defined by data on files.

Link Enhancements

• Links can now also be represented by VRML models for visualization.

• Automatic stiffness calculation for semi-rigid Generic Parts.

• Reference geometry for visualization can be included in the model

Guide panel

A guide panel with messages, Done and Cancel buttons leads the user through the modeling.

UI features

• Icons have been added on the main nodes of the model tree in the Object Browser view, increasing the readability of the model.

• Multiple file references can now be created in one operation.

• The path to the model link repository can now be relative.

• Curves can now have an automatically defined description.

• Auto coloring of links when they are imported.

• Prescribed motions on triads is available

Reduced storage requirements

The matrices mapping internal DOFs to external DOFs, the B- and E-matrix, may now be stored in single precision to reduce disk usage.

Model file template

When starting Fedem or when doing a "New" command, a template model file is loaded containing some commonly used Graph and Animation definitions etc. The user may modify the contents of this file or change to another model file.

Remote solving

Remote solving enables execution of solver operations on a remote computer with file access to the actual Fedem model and result database.

Extended Nastran Bulk Data support

The following Nastran Bulk Data entries is added:

1. CROD/PROD

2. CONROD

3. CWELD/PWELD
