Finite Elements for Experts. ECCON IPP is a software for pre- and postprocessing three-dimensional finite elements method (FEM) calculations.

The software was developed in-house and is used in all kinds of tasks, ranging from general mechanical engineering to civil engineering. The use of numerous individual calculation tools and problem solving manuals leads to results in a very short time. Numerous individual calculation tools and problem-solving manuals combined with a fast and efficient analysis of individual constructions allow for new and innovative solutions and concepts in mechanical engineering and architecture.

Eccon-Ipp interactive finite elemente pre- and postprocessor

Shortcuts ‘ECCON-IPP’

ECCON-IPP is an interactive pre- and postprocessor, that offers all advantages of a finite element calculation. The user can use many individual tools for generating and presenting of results. The consequent utilisation of the colour displays for presentation increases the reliability and productivity of FE-calculations, whereby new dimensions for interpretation of the results are being opened. ECCON-IPP produces the whole input and reads the calculation results from FENAS.

ECCOn Finite Elements


Finite Element Nonlinear Analysis of Structures is a program to calculate nonlinear behavior of beam, shell and solid elements. It is able to perform linear and nonlinear calculations, elastically supported elements, inactive elements, dynamic, calculation, elasto-plastic material behavior, eigenvalue extraction, large deformations, nonlinear temperature fields.

The following element types are available: gapelements, cable elements, space frames, linear, quadratic and hybride shells, linear and quadratic solids, 1D, 2D and 3D temperature elements.
