STRUREL 2020 is available

The new release of STRUREL is available. We have added many helpful features to our software packages COMREL, SYSREL and COSTREL. Most notably, we extended the external interface of STRUREL: All our packages can now be coupled to C/C++, FORTRAN, Maplesoft Maple, Wolfram Mathematica, MathWorks Matlab, Python and Ruby. It is now straight-forward to use an external interface of STRUREL in your analysis. We also pushed our Add-On Feature to a new level, so that you can work with complex and challenging limit-state functions and share your projects with others.

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.
