Release News FEMFAT 5.4.1

With FEMFAT 5.4.1, the new FEMFAT (intermediate) version is now available for download.

You can expect a colorful mixture of new functionalities and numerous program improvements. Selected points are briefly introduced below: 

 

 

Multi-Material File

As of now, FEMFAT material files (* .ffd) can contain several different material definitions. Advantage: all definitions can be read in at once, the sequential reading of individual ffd files can be omitted.

Interfaces

Some innovations concern the ABAQUS interface: up to now exactly one odb library was installed in FEMFAT for a certain ABAQUS version. This meant that an odb update was required when importing older files. For large files, this process could lead to significantly longer import times.

In contrast, several odb libraries can now be installed at the same time. When importing an odb file, FEMFAT automatically searches for the correct library.

The support of „Includes“ also deserves special mention. These are processed correctly when importing structural data in FEMFAT. This improvement also affects the NASTRAN interface.

As of FEMFAT 5.4.1 CENTROID stresses are also supported.

VISUALIZER

With some improvements, the VISUALIZER can further expand its position as a user-friendly postprocessor: the display has been expanded to include local node properties such as material, temperature, surface roughness, technological size and range of dispersion.

Subwindows with the local detailed results can now also be requested for all selected nodes. These are automatically arranged intelligently so that you do not lose track of them.

On the xMCF interface side, an upgrade to version 3.0 is to be reported.

WELD

Additional options for stress averaging have been implemented in WELD. As a result, the weld seam evaluation can be carried out, for example, with un-averaged nodal stresses.

For greater flexibility, it is now also possible to define parameters for determining the assessment distance in the hot spot method.

SPECTRAL

The evaluation of short fiber reinforced plastics is now also possible in SPECTRAL.

Rainflow-Matrix-Viewer

Some small but fine enhancements concern a rather inconspicuous and nevertheless frequently used application in FEMFAT, the Rainflow Matrix Viewer. This has been fundamentally revised and equipped with new, helpful functions. Among them are picking individual bars of the rainflow matrix (including the result display) as well as standalone option and opening any FEMFAT rainflow matrix files.

Additional Features

New functionalities facilitate the evaluation of results through the automatic identification and group generation of local extreme values and their output in table form in the report file (* .pro).
