Reliable, accurate and user-friendly - the "Software" portfolio of Steinmüller Engineering GmbH
The high quality standards of our products demand a software environment that effectively supports our product design. Our trained users develop optimal solutions to meet the technical requirements, using a combination of commercial and in-house developed programs for process and mechanical engineering. Our range of in-house tools is now available to you.
Over decades we have developed, validated and certified various in-house software tools, e.g. for heat transfer and flow simulation. These programs, initially developed for internal engineering purposes, are now available to our customers and partners through license agreements.
Most prominent is our software for dimensioning of boilers and other complex heat exchanger systems. Visit DimBo®.
also forms the basis for our online plant monitoring and diagnostic tool PRS, assisting our customers to optimise their plants in terms of efficiency, reliability and lifetime. Visit the Digital Twin.
A group of in-house software tools has been converted into web applications to familiarize you with our products and services. This collection covers various process applications and supports users to calculate desired parameters. All these tools are available to you at no cost and do not require any additional installation. Visit the Tools.
Our in-house developed tools are accompanied by highly sophisticated commercial tools, which have proven suitable for our product design.
The computational fluid dynamics (CFD) tool ANSYS Fluent is used to model three-dimensional single and multiphase flows, including heat transfer and chemical reactions. CFD is not only applied to investigate and optimize our own products, but is also used to analyze our customers’ existing equipment. Application examples include low NOx burners, complex duct systems for gas and particles, flue gas cleaning devices and water/steam systems. The associated models consist of up to 100 million volume elements and are efficiently solved on Steinmüller Engineering’s high performance cluster. Visit the HPC Cluster page section.
RECOM-AIOLOS is a 3D-CFD Code which is tailored to simulate reacting flows in industrial furnaces and boilers. At Steinmüller Engineering AIOLOS is mainly applied to obtain insight into the combustion process by dividing the furnace geometry into several 10 million volume cells. Investigations include design verification and optimization of low NOx burners, prediction of emissions and many other aspects. Although a complex flow is simulated, results are available within reasonable time by using Steinmüller Engineering’s high performance cluster. Visit the HPC Cluster.
ProSim Plus HNO3
Our simulation software ProSim enables us to recalculate your nitric acid plant to increase plant efficiency or to identify bottlenecks in a planned increase in output. In combination with our in-house program we also consider the waste heat boiler as a critical key component in the plant. The advantages of the ProSim software are combined with the know-how of our experienced engineers to achieve the best possible solution for you. Visit ProSim.
Beyond the steam generator itself, if the entire water-steam circuit of a power generation process is being studied, the appropriate tool for the planning, design and optimization of the plant is EBSILON Professional of STEAG.
The mechanical design includes both static and strength calculations with the following commercial software tools.
PROBAD by SIGMA is used for pressure part calculations according to standard regulations (e.g. EN 12952, ASME I, ASME VIII/1 or AD2000).
ANSYS is used as FEM software for verifications not covered by standardized code calculations and for the optimization of components. Larger models with their high demand for CPU time are processed on our Steinmüller Engineering’s high performance cluster. Visit the HPC Cluster.
We also use the ROHR2 from SIGMA for static calculations and for elasticity analysis of piping systems (e.g. according to EN 13480 or ASME B31). In addition to the primary weight load from stationary internal pressure, secondary loads from thermal expansion as well as occasional loads, e.g. wind, earthquake and other external forces are considered.
RSTAB and RFEM
Steel structures and their required static verification are managed using the RSTAB (framework calculation) and RFEM (finite element) software from Dlubal.
All of the commercial tools mentioned above are embedded with multiple licenses in our company IT. The knowledge base of our trained users remains up to date through continuous use and targeted training programs.
The entire range of CAD products from AUTODESK are utilized by our design department.
AutoCAD Mechanical is used for the traditional draft production. The design drawings serve as the product documentation and are passed on to the workshop as the basis for the manufacturing of the products.
Using Inventor we develop complex geometries presented in a 3-D model before the workshop drawings are derived.
Piping and instrumentation diagrams are not only drawn, but moreover by using the database-aided planning tool AutoCAD Plant P&ID, such systems, complete with control devices and measuring instruments, are configured in a way that allows lists of components and the associated technical data to be generated.
Finally, AutoCAD Plant 3D is used for plant layout including equipment and piping. On this basis entire systems with multiple components and their connecting piping are planned such that collisions are avoided and accessibility is guaranteed at all times.
AutoCAD Plant 3D is used to export data, for example, to the Rohr 2 program to perform the related static calculations for the pipe isometrics and to RStab for the static calculations of the supporting framework structure (see statics and strength). If required, we are flexible to work with alternative CAD models.
Product specific software combined with the know-how of our experienced engineers responsible for the tasks ensure a highly efficient design process that is closely integrated with the related engineering tasks.
CFD (Computational Fluid Dynamics) and HPC (High Performance Computing) are closely related at Steinmüller Engineering. Over recent years the hardware development and the advanced development of CFD software make it possible to perform complex calculations in parallel, on multiple processor cores. As a result, calculations that were once reserved for the computer centers of universities or large companies can now be handled. Today we perform such simulations with our own in-house hardware and professional software.
- ANSYS Fluent including HPC Workgroup 256 for massive parallel processing
- Job scheduler for the assignment of processor cores to the pending simulations
- HPC Cluster based on Dell hardware with 28 compute nodes and in total 560 processor cores
- Several high-performance workstations for model development as well as pre- and post-processing
Multiple simulations are carried out simultaneously with each simulation being assigned an individual number of processor cores.
The tailored hardware configuration was developed together with specialized partners. Software packages and hardware are attuned to achieve maximum computational performance.
