The finite element program SRPIPE by EDAC (Dr. K. Sachs) was used for a large number of various piping system calculations. This program is suitable for static and dynamic calculations, as well as for all common stress analysis methods (ASME Class 1, 2 and 3, ANSI B31.1 and B31.3; FDBR).

The finite element program KWUROHR by KWU has been used for a very large number of various piping system calculations. This program is suitable for static and dynamic calculations, as well as for all common stress analysis methods (ASME Class 1, 2 and 3, ANSI B31.1 and B31.3).

The program SAP5 by the University of Southern California (UCLA) in Los Angeles was also used for a very large number of different computational tasks. This program is suitable for static (thermal) and all kinds of dynamic calculations and corresponding graphical output of the results. There are a number of self-developed additional programs for post processing - BRICK8, Plate1, etc.

The ANSYS program by ANSYS Inc. has also been used for a large number of selected linear-elastic calculation tasks. This program is suitable for static and dynamic calculations with a variety of different element types and corresponding graphical output of the calculation results.

The program ANSR by the University of Berkeley in California has also been used for calculation of selected tasks. This program is mainly suitable for nonlinear static and dynamic calculations (including the corresponding graphical output of results).

The program IMMI by Woelfel Measurement Systems and Software GmbH (Hoechstadt b. Würzburg) was used for a large number of different 3D noise propagation studies. This program is suitable for virtually all kinds of acoustic calculation tasks (outdoor sound propagation algorithms for solution after international standards and sound propagation in enclosed spaces) and offers a variety of graphical representations of the results of calculation.

The computer program INSUL, (Version 9.0.19) of the company MARSHALL DAY Acoustics allows for the determination of the airborne and impact sound Insulation Values or their frequency-dependent gradients for single, double and triple-shell components. The results are presented in the form of graphics and tables. 

The archiPHYSIK program was used for different tasks (determining the U-value of complex composite components, vapor diffusion, condensation, heat demand, heat storage, creating the energy certificate, etc.). The calculations are carried out by various guidelines and national standards.
