Software

The mechanical design includes both static and strength calculations with the following commercial software tools.

PROBAD

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 FEM

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.

ROHR2

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

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.

Inventor

Using Inventor we develop complex geometries presented in a 3-D model before the workshop drawings are derived.

Plant P&ID

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.

Plant 3D

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.

Equipment

• ANSYS Fluent including HPC Workgroup 256 for massive parallel processing
• RECOM-AIOLOS
• 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.
