COMREL 10 released

We released the latest version of Comrel: COMREL 10.

Major improvements include:(i) Limit-state functions entered in Comrel are automatically expressed in mathematical notation. (ii) The help system has been revised. (iii) The symbolic expression editor supports undo/redo.

Please note: Since Comrel 9.5 users can directly load limit-state functions written in C/C++, FORTRAN and Matlab into Comrel. Furthermore, data, documentation material and other information can be incorporated into the associated user-made libraries.

You can download the demo version of COMREL 10 from http://strurel.de/demoversion.html

Version 9.5 of COMREL is available!

The new release of COMREL comes with numerous improvements. The most notable new features are: (i) Limit-state functions coded in Python can now directly be analyzed. (ii) You can now easily develop your own interfaces to external programs by employing the new Sturel Add-On (SAO) feature. (iii) The COMREL manual is now directly integrated into the graphical user interface.

Improved GUI of COMREL in upcoming version

The release of Comrel 9.5 is in the offing. In the new version, the documentation is now directly embedded in the graphical user-interface (GUI). Moreover, the symbolic expressions editor (that is used to define limit-state functions) now comes with an ‘undo & redo’ feature that allows you to easily revert erroneous edits.

The application also comes with improved usability in shortcuts.

Presented Strurel at the UNCECOMP conference in Rhodos

The 2nd International Conference on Uncertainty Quantification in Computational Sciences and Engineering (UNCECOMP) took place at Rhodes Island, Greece. We presented the different modules of Strurel.

Abstract: Strurel is a leading commercial general-purpose software package for probabilistic modeling and structural reliability assessment. Strurel includes software modules with state-of-the-art computational methods for component and system reliability analysis. These include the First and Second Order Reliability methods (FORM/SORM) and sampling based method including Monte Carlo simulation, subset simulation, importance sampling, line sampling, directional simulation and adaptive importance sampling. Strurel can handle static as well as time-dependent problems, and supports a wide range of probabilistic models encountered in structural reliability. It also includes a set of tools for the calibration of safety factors in structural design. Strurel comes with an easy to use graphical user interface and additionally enables coupling of limit-state functions with user-defined system models through an interface with external programs.
The computational core of Strurel has been coupled with the finite element package SOFiSTiK in a new module called RELY that comes as part of the SOFiSTiK software package. RELY is specifically designed to perform reliability analysis employing SOFiSTiK finite element models. In RELY, the engineering system of interest is modeled using the full capabilities of the SOFiSTiK finite element package; existing SOFiSTiK finite element models can be readily employed for reliability analysis.
We demonstrate Strurel and RELY on two example applications. Firstly, a reliability analysis using a limit-state function for a pressure vessel coded in Matlab is conducted in Strurel. Secondly, a reliability analysis of a design concept for a submerged floating tube bridge is performed with RELY.
