Impact is an explicit Finite Element Program Suite which simulates dynamic impact events. It has a range of elements, contact handling and different material laws. Models can be created, solved and analyzed with the included pre- and postprocessor. Impact is based on an Explicit Time stepping algorithm. These kind of codes are used to simulate dynamic phenomena such as car crashes and similar, usually involving large deformations.

Fachwerk calculates strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

Fachwerk3D calculates three-dimensional strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

Open channels hydraulics is very important part of hydraulic and civil engineering. Finding critical depth in open channel flows is a basic task in this field. This is an application for calculating critical depth in open channels flow.

PSA(Program for Structural Analysis) is able to analyse Framed structures using FEM(Direct Stiffness Method). Apart from giving the analysed results, PSA is able to give user the various stiffness Matrices generated during the analysis, as web page.

Soil Sieve Test Analyzer is an application for analyzing results of sieve test. Sieve Test is part of Grading Test in Geotechnical Engineering that is part of Civil Engineering to classify mechanical soil behavior.
