The Beginnings

With his doctorate in 1999, Dr. Dirk Bohmann developed the foundation for the finite element software MEPLA.
His innovative approach to laminated glass panes made it possible for the first time to realistically simulate visco-elastic deformation and stress behavior. In order to accelerate market entry, Dr. Bohmann concluded a cooperation agreement with SJ Software GmbH, which programmed the front end he designed for entering the data, while the complex calculation core was always developed and maintained entirely by Dr. Bohmann. His automated and efficient procedure was very well received in the industry because, in contrast to conventional FE software, it enabled the fast and precise calculation of all glazing geometries and glass structures in a short time.
Professional expertise expanded

During his civil engineering studies at the Technical University of Darmstadt, Leon Bohmann focused on the mechanical fundamentals that are crucial for the further development of the MEPLA core. His expertise in the mechanics of materials, micromechanics, continuum mechanics and glass construction expanded the scientific foundation of the program. In his Bachelor's thesis, he developed an independent FE program for modelling hyperelastic materials in three-dimensional systems. During his Master's degree, he specialized further in glass construction and polymers as well as advanced concepts of fracture mechanics. His master's thesis on the fracture behavior of thermally toughened glass panes will ideally complement his expertise in MEPLA technology.
MEPLA Software GmbH – All expertise under one roof

Mepla Software GmbH was founded in August 2024, as the end of the cooperation agreement with SJ Software GmbH was already looming. It was terminated completely in February 2025, which makes SJ Mepla 5.0 the last distributed version. This strategic decision brought all development and sales expertise into one company. It is important to emphasize that the complex mathematical calculation core - the heart of the software - was always developed exclusively by Dr. Dirk Bohmann and is now fully located at Mepla Software GmbH. SJ Software GmbH has neither the know-how nor the rights to the calculation and visualisation core.
Since February 2025, Mepla Software GmbH has combined the development of the user interface and the scientific calculation core under one roof with MEPLA Pro. This integration not only ensures optimum coordination of all components, but also offers our customers direct access to leading expertise in the field of finite element analysis for glazing systems. With Dr. Dirk Bohmann and Leon Bohmann, M.Sc. as managing directors, our company has the academic depth and practical experience that is essential for sophisticated simulation solutions. The entire technical competence and further development now lies exclusively with us - Mepla Software GmbH.
