The new release of Strurel including Comrel, Sysrel and Costrel comes with considerably improved handling of the external interfaces to Maplesoft Maple, Wolfram Research Mathematica, MathWorks Matlab, Python and Ruby. The major new feature is a build-in Script Editor with syntax highlighting for all interfaced scripting languages. If an error occurs in a (limit-state) function evaluated through an external interface script, Strurel highlights the script position that caused the error. Furthermore, Strurel reports the state the variables had when the error occured. Strurel can now handle MAT-files. MAT-files can be used to store or load scalars, vectors or matrices within the external scripts linked to Strurel. MAT-files are primarily used in the context of Matlab, but can also be accessed from Python, Maple, Mathematica or Ruby. You no longer have to manually restart the interfaced external engine, when you change the corresponding script file. Other notable features are: (i) Retranslator Mathematical Formulas (RMF) converts expressions in Symbolic notation of Strurel to mathematical notation. (ii) The Help system is completely based on a PDF standard. A context sensitive help for the Symbolic Expressions Editor is implemented. (iii) In order to use the functionality of Maple, Mathematica, Matlab, Python and Ruby a set of extremly simplified interface functions has been implemented. (iv) You can now easily design your own Strurel Add-Ons by using an integrated SAO-Creator. The Add-on creator allows you to easily distribute your projects, while making sure that the project is distributed with all required files, including a project documentation.
STRUREL is a collection of programs for stuructural reliability analysis. More details can be found here.
The core package is COMREL for component reliability analysis.
The additional package is SYSREL for system reliability analysis.
The next additional package is COSTREL for reliability based optimization.
In reliability analysis, the goal is to assess the performance of models of varying complexity. Additionally to internal Symbolic language, Strurel allows you to use limit-state functions coded in C/C++, Fortran, Maple, Mathematica, Matlab, Python and Ruby.
As a demonstration of the new capabilities we have taken from literature a well known example-structure: a plane truss with 23 bars and vertical loading. The failure criterion was deformation greater 11 cm in the middle of the lower girder. This example was analysed by all 5 engines with identical results in terms of probaility of failure. Additionally, for extended visualisation, deformations plot were realised using graphical facilities of the corresponding engine.

You can develop your own Strurel Add-Ons using SAO SDK or the integrated SAO-Creator to achieve external environments by interfaces implemented in Strurel. State-of-the-art reliability methods of Strurel are used in module RELY of SOFiSTIK also. More details can be found here.
MAT-files can be used to store or load scalars, vectors or matrices within the external scripts linked to Strurel. MAT-files are primarily used in the context of Matlab, but can also be accessed from Python, Maple, Mathematica or Ruby.
We analysed a complex spatial truss taken from literature.
On the education page, you will find a series of video tutorials that demonstrate the use of the STRUREL programs.
Due to material deficiencies and changes in safety requirements, existing overhead transmission towers must undergo a verification of their reliability. STRUREL powers the software P242 for FE based reliability analysis of these towers, which was developed in collaboration with major German electrical infrastructure companies. Due to its user-friendly and effective design, the software is used efficiently to verify 1000s of transmission towers.
STRUREL supported the design and manufacturing of critical components of aerospace structures, including the high-strength steel booster case of Ariane 5 for which an exhaustive reliability assessment was performed. The reliability updating capabilities of STRUREL allowed optimizing the expensive proof-tests that are part of the manufacturing process.
STRUREL was central in verifying and demonstrating the reliability of the Storebæltsbroen cable bridge. The effect of cable failures on the reliability of the bridge was investigated with the unique system reliability tools incorporated in STRUREL. These allow to efficiently assess systems with large numbers of failure modes.
